Catalog service platform for deploying applications and services

ABSTRACT

A service provider system may implement an enterprise catalog service that manages catalogs or portfolios of software products (e.g., desktop applications and server products) on behalf of service provider customer organizations. Through the enterprise catalog service, an administrator in a customer organization may discover, select, and ingest products (e.g., based on their features, pricing, and terms), and may add them to catalogs or portfolios for subsequent use by end users in the organization. The administrator may apply constraints on product use and limit product access to particular end users. The products may include third party products that are made available through the enterprise catalog service and a customer&#39;s own applications. The enterprise catalog service may monitor usage of third party products and bill the customer organization. Products managed by the enterprise catalog service may be deployed through an application fulfillment platform or resource stack management platform.

BACKGROUND

Many companies and other organizations operate computer networks that interconnect numerous computing systems to support their operations, such as with the computing systems being co-located (e.g., as part of a local network) or instead located in multiple distinct geographical locations (e.g., connected via one or more private or public intermediate networks). For example, data centers housing significant numbers of interconnected computing systems have become commonplace, such as private data centers that are operated by and on behalf of a single organization, and public data centers that are operated by entities as businesses to provide computing resources to customers or clients. Some public data center operators provide network access, power, and secure installation facilities for hardware owned by various clients, while other public data center operators provide “full service” facilities that also include hardware resources made available for use by their clients. However, as the scale and scope of typical data centers has increased, the tasks of provisioning, administering, and managing the physical computing resources have become increasingly complicated.

Many large companies are attempting to move data center resources to cloud computing environments. These companies may use large amounts of desktop computing software that must be procured, kept up-to-date, and distributed across many desktop computers in multiple locations. For a large enterprise, it can be difficult to keep all of the applications they may wish to use up to date using the traditional approach of physically installing applications on each machine. For example, deploying and managing applications at scale is difficult, complex and requires expensive on premise infrastructure. In addition, updates and patches are complex to deploy without affecting user productivity, and legacy applications typically only run on older operation system versions. It can also be difficult for a large enterprise to deploy applications on-demand and their own line-of-business applications. In many cases, there is a lack of transparency into cost controls, spending and usage related to desktop applications and software services. Therefore, large enterprises can miss opportunities for license synergies across the organization.

For example, within a large enterprise, individual business units often procure their own software and services. When this is not done in a controlled fashion, the resulting sprawl of unapproved products creates compliance risks that administrators have to address. Different organizations have taken a variety of approaches to increase standardization and enforce compliance. Some attempted to address these issues by setting policies centrally, educating users, and relying on them to comply. Often, users had to bear most of the burden for compliance, impacting productivity and increasing risk. Other organizations attempted to address these issues by centralizing control, so that only a small and trusted set of users could have access to the most powerful tools, sacrificing agility and self-service.

DETAILED DESCRIPTION

The systems and methods described herein for implementing an enterprise catalog service may, in various embodiments, enable administrators within customer organizations to create catalogs and portfolios of software products (e.g., enterprise-wide catalogs, portfolios, and/or other catalogs containing desktop applications and/or server products) and to share them with specific sets of users. For example, through the enterprise catalog service, administrators may be able to offer a standard set of products for common use cases to the end users in their organizations that meet their organizational goals and requirements. In some embodiments, the enterprise catalog service may allow administrators (e.g., IT administrators or buyers) to discover software products, provision service provider resources on which to deploy those software products, and manage those software products through a service provider management console. The use of the enterprise catalog services described herein may benefit customer organizations by increasing standardization, enforcing compliance with organizational policies, reducing the costs of compliance, and improving agility. In some embodiments, once the software products managed by the enterprise catalog service are in use, administrators can track their usage and monitor health through the service, in order to provide the best possible experience for their users.

In some embodiments, end users may access the enterprise catalog service through an end user console to discover software products and provision them for their common use cases. For example, an administrator may define a product once and enable self-service and repeated use by a group of end users. After provisioning the products, users may track their usage, monitor health, and manage the resources through the end user console or through the service provider management console. In one example, a development manager might create a product for a standard development and test environment that will be used by the developers on his team. Each developer can provision and use the development and test environment in a self-service fashion, and then shut it down (de-provision it) when it is no longer needed.

As described above, in some embodiments, administrators may access the enterprise catalog service through a service provider management console to create and manage catalogs or portfolios. Each catalog (e.g., a default or enterprise-wide catalog or one of multiple private catalogs or portfolios that are accessible only by a subset of the end users in the customer organization) and/or portfolio may contains a set of products. The products in any given catalog may all be of the same type or may include products of different types, in different embodiments. For example, a given catalog or portfolio may include one or more desktop applications (e.g., desktop applications packaged as machine images, application binaries or other executable objects), one or more virtualized application packages (e.g., applications packaged for delivery to desktops on physical computing devices and/or one or more virtual desktop instances, or resource stack templates, dependent on configuration settings selected for the catalog/portfolio by the administrator that created it.

The enterprise catalog service may, in some embodiments, provide access to product listings from third parties (i.e., entities other than the service provider customers and the service provider itself). For example, in some embodiments, the enterprise catalog service may include (or provide an interface to) a product discovery service through which administrators and users can discover and/or obtain access to software products that were developed by (or are published and/or sourced by) two or more independent software vendors (ISVs). For example, an administrator in an organization that is a customer of the enterprise catalog service may procure a product through the product discovery service, customize it, configure data protection settings appropriate for the customer organization, and publish it to end users in the customer organization through an enterprise-wide or private catalog that the administrator owns and/or controls. In this way, administrators may be able to not only ingest their own company products but may also be able to find and subscribe to products from external sources. The products ingested by the enterprise catalog service for inclusion in a customer organization's catalog may require paid subscriptions or licensing fees (e.g., fees charged hourly, monthly, annually, or using any other pricing schedule), or may be free for service provider customers and their end users to use.

In some embodiments, desktop applications that are included in a private catalog or portfolio and managed by the enterprise catalog service on behalf of a service provider customer organization may be deployed to end users in the customer organization through an application fulfillment platform that interacts with the enterprise catalog service. For example, an application fulfillment platform may provide on-demand delivery and installation of applications to virtual desktop instances in a cloud computing environment for the benefit of end users (e.g., employees or members of a business, enterprise, or other organization that is a customer of the service provider). In some embodiments, the application fulfillment platform may employ a variety of services to manage collections of desktop applications that are maintained by the enterprise catalog service (e.g., catalogs or portfolios of desktop applications) and to deliver virtualized application packages to end user machines or virtual desktop instances. In some embodiments, end users may access the enterprise catalog service through an end user console of the application fulfillment platform.

As noted above, in some embodiments, customers of a service provider (e.g., buyers or IT administrators within an enterprise) may be able to discover and subscribe to third party desktop applications (or desktop applications that have been purchased or licensed from a third party by the service provider) on-demand and make them available to their end users on virtual desktop instances. In addition, an IT administrator of a customer may be able to publish and manage the customer's own line-of-business desktop applications, which may be accessible only for their end users.

In various embodiments, the application fulfillment platforms described herein may provide IT administrators full control over their virtual desktop instances with dynamic application management tools. For example, IT administrators in customer organizations may be able to build application catalogs or portfolios (e.g., using an enterprise catalog service such as those described herein) for their end users that are composed of applications from sourced through the platform and/or their own private applications, where a portfolio is a collection of applications and corresponding constraints (including maintenance schedules and license types), and that can be assigned to end users or groups of users. Note that as used herein, references to “assigning” a product or portfolio to an end user or to a group of end users may describe actions or operations by which the end user or group of end users is granted permission to install, subscribe to, or launch the product (or the products in the portfolio). In some embodiments, these actions or operations to grant permissions to an end user or group of end users may also be described as “creating an entitlement” to a product or portfolio for an end user or group of end users. In some embodiments, customers may allow their end users to install applications on-demand. IT administrators may interact with the application fulfillment platforms through a management console (sometimes referred to herein as a service provider system console or an administrator console) that offers IT administrators access to the tools for managing catalogs or portfolios (e.g., catalogs or portfolios of desktop applications that are maintained by the enterprise catalog service), application updates, constraints, constraint groups, application licenses and/or their own private applications. The systems described herein may allow customers to efficiently manage their software application spending with detailed usage reports and monthly subscriptions. Because the service provider may be able to negotiate bulk and/or wholesale prices from application vendors, the service provider may be able to offer them to customer (e.g., individually or in bundles containing groups of popular applications) with competitive pricing.

As described herein, application fulfillment platforms may provide a self-service model to end users through an application on their virtual desktop instances. For example, through this application (which is referred to herein as a desktop application management module), end users can discover and manage an application portfolio that best fits their needs, with the ability to install applications marked as optional by their IT administrators. IT administrators may also have the option to authorize their users to be able to request access to additional applications and/or to receive notifications of new applications or application updates as they become available.

Note that in the context of the services described herein, the terms “customer” and “buyer” may refer to an enterprise, a business, or another organization that receives services (e.g., catalog services, application management services, and/or software product fulfillment services) from a service provider on behalf of their end users. In this context, the term “sellers” may refer to software vendors that provide their applications for use within the application fulfillment platforms described herein, and the terms “users” and “end users” may refer to employees or members of the enterprise, business, or other organization that receives services on their behalf from the service provider. In various embodiments, users may access software products that are fulfilled through the platforms and services described herein on their own computing resources instances (e.g., on end user machines and/or virtual desktop instances) or may invoke the execution of server products (e.g., services implemented by resource stacks of service provider resources) on their behalf. Note that in various embodiments, an enterprise catalog service “user” may represent an identity and access management role (e.g., a child account of a root account for a service provider customer or service provider customer organization) or may be an end user in a customer organization (e.g., an active directory user), and the enterprise catalog service may support groups of both of these types of users (e.g., active directory groups or identity and access management groups). Note also that the term “active directory”, as used herein, may more generally refer to an active directory, a cloud directory, or another technology for managing users and/or other resources through a directory.

In some embodiments, applications (e.g., desktop applications) may be delivered to various end users' virtual desktop instances using an application virtualization technology that encapsulates and isolates applications in dedicated containers. For example, a packaging service implemented on the application fulfillment platform may be configured to transform applications into virtualized application packages and to deliver them to virtual desktop instances or physical desktops running over an operating system on an end user's machine. The virtualized application packages, when executed, may perform and behave as if they are natively installed, without the need for actual installation.

As described herein, an application fulfillment platform may offer customers (or more specifically, IT administrators of those customers) the ability to provision applications on-demand at scale while maintaining centralized control, security and compliance. For example, in some embodiments, these platforms (and corresponding services thereof) may be integrated with a management console through which the IT administrators may discover and subscribe to a broad selection of applications from a variety of sources, build catalogs and/or portfolios of applications from a variety of sources and having a variety of subscription/licensing models, control access to applications with granular access policy enforcement on a per user basis, manage application updates, access detailed usage reports for their enterprise, application portfolios and end users, and/or monitor real-time installs as well as license activation on a per application basis.

As noted above, the application fulfillment platforms described herein may be integrated with or may be configured to operate in conjunction with an enterprise catalog service, such as those described herein. As described herein, administrators may create catalogs or portfolios of products and resources from a variety of suppliers, and may share them with a specific set of users. These products may include not only desktop applications to be delivered to virtual desktop instances as virtualized application packages, but may also include server products (e.g., server-side applications to be executed on a server on behalf of a customer or end user) and/or applications to be delivered as executable files (e.g., application binaries or machine images) to be installed on an end user's computing device or virtual desktop instance. In some embodiments, once the enterprise catalog service is used to create a catalog or portfolio of desktop applications, these applications may be installed as virtualized application packages by end user at a later time (e.g., on-demand). The integration of the enterprise catalog service with a resource stack management service through which server products may be defined and deployed in described in more detail below, according to various embodiments.

The enterprise catalog services described herein may be implemented in whole or in part on an enterprise catalog service platform that includes (or operates in conjunction with) various components and services in the service provider network that are used in managing collections of software products on behalf of service provider customer organizations and their end users. For example, the enterprise catalog service platform may include (or provide an interface to) a product discovery service, robust catalog management tools, tools for authoring and managing the lifecycles of products, product listings, and product offerings, a catalog store (e.g., an indexed, revision-controlled document store where all products and offers are mastered), a lifecycle system responsible for validation, approval, and promotion workflow steps, and a catalog publishing system.

TERMINOLOGY

In the context of the enterprise catalog services described herein, the term “product” may refer to any resource (e.g., a machine image, resource stack template, desktop application binary or virtualized application package) that has been prepared for consumption by other users and that may be included in a catalog of such resources or listed in a portfolio of such resources. Products may be ingested by an enterprise catalog service through the IT administrator console and, once added to a catalog or portfolio, may be fulfilled (which may also be referred to as being launched) by end users through an end user console. In various embodiments, actions that can be taken on a product may include one or more of the following:

1. Create

In some embodiments, the actions that can be taken on an offer may include the following:

1. Create

2. Read

3. Update (Change price, Change availability, Change accessibility)

4. Publish views

In the context of the enterprise catalog services described herein, the term “listing” may refer to a human readable view of a combination of products and offers. There may be different ways to present a listing, in different embodiments, the goal of which is to allow administrators, buyers and/or end users to make informed purchase decisions from a specific business context. Ratings, and reviews, and recommendations may also be included in (or associated with) listings. Listings may be mutable and may be consolidated, in some embodiments. Various enterprise catalog service APIs associated with listings are shown below.

In the context of the enterprise catalog services described herein, the term “subscription” may refer to a record of an agreement of an offer by a user. This agreement entitles a user to the products specified in the chosen terms of the offer. Additional parameters of the terms may also be collected in a subscription. In some embodiments, the actions that can be taken on a subscription may include the following:

1. Create

2. Read

3. Update (Renew, End)

In the context of the enterprise catalog services described herein, an entitlement may be a collection of allowed product actions for each user. In some embodiments, the actions that can be taken on an entitlement may include the following:

1. Create, Update, Delete (private)

From the standpoint of a high level software architecture, a service provider platform that implements an enterprise catalog service such as those described herein may be comprised of the following components: a catalog service, a service catalog runtime, an inbox service, a resource stack management service, one or more administrator/management consoles, and one or more end user consoles, each of which may provide a portion of the functionality of the enterprise catalog service. The catalog service may be the core storage and version control mechanism for the enterprise catalog service. IT administrators may create and publish products and product versions that are stored in the catalog service, and IT administrators create portfolios and assign products to portfolios. Catalog information, portfolios and association between catalogs or portfolios and products may be stored in the catalog service. The service catalog runtime may be responsible for fulfilling products (e.g., products defined using resource stack templates). The service catalog runtime may also provide support for “managed services” whereby the end-user does not have access to the service provider resources that are created when deploying a product.

In some embodiments, an inbox service may allow various service provider services to send targeted, actionable “messages” to users e.g., (administrators or end users). The inbox service may define the notion of an InBox as a target for such messages. The inbox service may allow administrators to define who has access to various messages and where notifications are sent when messages arrive in a particular InBox. In some embodiments, the enterprise catalog service may uses the resource stack management service as the underlying fulfillment engine for server products. In various embodiments, one or more administrator/management consoles may provide graphical user interfaces for creating and managing products and portfolios, and one or more end user consoles may provide graphical user interfaces for launching and managing products.

Note that in some embodiments, a workflow service may be used to run workflows to complete various tasks in conjunction with the enterprise catalog service, the application fulfillment platform, or the resource stack management service. For example, in some embodiments, there may be a separate workflow for each operation performed on a resource stack. In a specific example, when a call is made to launch a resource stack, a “LaunchStack” workflow (e.g., one that is specific to that combination of user and resource stack name) may be created to monitor and harvest any information from the resource stack. The workflow service may also provide a synchronization mechanism to ensure that only certain operations are being performed at the same time (for example, prevent an update operation from starting if the target resource stack is still in the process of being created).

FIG. 1 is a block diagram illustrating a portion of a service provider system that implements an enterprise catalog service, according to at least one embodiment. The system includes an enterprise catalog service platform through which IT administrators within service provider customer organizations (e.g., enterprises that receive computing services from the service provider) can manage catalogs and/or portfolios of desktop applications and/or server products, as well as usage policies (e.g., constraints on the use of those desktop applications and/or server products) for their end users. As illustrated in FIG. 1, system 100 may include an enterprise catalog service platform 108 (which may embody both a catalog service and a service catalog runtime, such as those described above) that is configured to create and manage one or more enterprise catalogs 118, private catalogs 122 and/or portfolios 120 on behalf of service provider customers and their end users. Note that, in some embodiments, at least some of private catalogs 122 may represent logical collections of products to which a respective end user or other principal has access (each of which may include products that are included in one or more portfolios 120). As described in more detail herein, an IT administrator 102 may interact with the enterprise catalog service platform 108 through a service provider management console 106 to create a desktop application, resource stack template, or resource stack instance; to select, ingest, and/or package desktop applications and server products for subsequent use by some or all of their end users; create collections of products (e.g., desktop applications and/or server products), such as enterprise-wide catalogs, private catalogs, or portfolios); assign products or collections of products to end users and/or end user groups (e.g., end users or end user groups having particular user identities and/or permissions 124); apply various constraints 136 on the use of the products; and/or set other configuration parameter values for the products or collections of products.

As illustrated in this example and described in more detail herein, there may be multiple methods for an IT administrator to add products to catalogs and/or portfolios and make them available for deployment to end users. For example, system 100 may include a resource stack template editor 104. In various embodiments, IT administrators, end users, or third party software providers (e.g., independent software vendors) may create resource stack templates using resource stack template editor 104 for server products that be uploaded directly to enterprise catalog service platform 108 or that may (if subsequently published) be discovered and ingested by the enterprise catalog service through product discovery service 110. System 100 may also include a desktop application authoring and ingestion tooling component 116. In various embodiments, IT administrators, end users, or third party software providers (e.g., independent software vendors) may create desktop applications using desktop application authoring and ingestion tooling component 116 that may (if subsequently published as a machine image, application binary, or other executable application package) be discovered and ingested by the enterprise catalog service through product discovery service 110. For example, in some embodiments, IT administrators or end users in a service provider customer organization may create and upload customer-specific desktop applications (e.g., line-of-business applications) through desktop application authoring and ingestion tooling component 116.

In some embodiments, product discovery service 110 may provide an interface through which third party products 112 (e.g., server products or desktop applications that have been published and/or packaged for potential ingestion by the enterprise catalog service) can be discovered. Product discovery service 110 may include a product selection and ingestion tooling component 114, which may be configured to retrieve and/or package products that are discovered through the product discovery service interface or that are uploaded through the product selection and ingestion tooling component 114, in different embodiments. In various embodiments, the products ingested by the enterprise catalog service may be leased and/or licensed by the service provider and/or by service provider customers for the benefit (and use) of end users in the service provider customer organizations.

In some embodiments, when a product (e.g., a desktop application or resource stack template for a server product) is selected by an IT administrator 102 and ingested by enterprise catalog service, it may be placed in a default catalog for the customer organization (such as enterprise catalog 118). The IT administrator 102 may then add it to one or more private catalogs 122 or portfolios 120, or may assign it directly to one or more user end users or end user groups having particular user identities and/or permissions 124. Similarly, when a server product instance is created (e.g., when a resource stack is constructed according to a resource stack template), it may be placed in the default catalog. The IT administrator 102 may then add it to one or more private catalogs 122 or portfolios 120, or may assign it directly to one or more end users or end user groups having particular user identities and/or permissions 124. Note that any constraints 136, groups of constraints, or configuration parameters that are selected for various products by the IT administrator (e.g., during their creation, ingestion, or addition to a particular catalog) may be applied to the products when they are added to other catalogs and/or portfolios. In some embodiments, these constraints, groups of constraints, or configuration parameters may be modified when they are added to other catalogs and/or portfolios, and/or additional constraints, groups of constraints, or configuration parameters may be applied to the products when they are added to other catalogs and/or portfolios to further restrict access to those products by end users or to further restrict the use of those products by end users who are authorized to access them.

As described in more detail herein, the products that are managed on behalf of service customer organizations by the enterprise catalog service implemented by system 100 (and, more specifically, by enterprise catalog system platform 108) may be deployed to end users through other components and services implemented by the service provider (e.g., on physical and virtual computing resources that are located and/or hosted on the service provider's network). For example, desktop applications may be deployed to desktops on various end users' physical devices and/or on virtual desktop instances (e.g., in response to requests from the end users to install, subscribe to or launch them) through desktop application fulfillment platform 126. In another example, server product instances may be constructed from resource stack templates (e.g., in response to requests from end users or IT administrators to deploy the services provided by the resource stacks) by resource stack management service 132.

In various embodiments, the end users of a service provider customer (shown as enterprise end users 134 in FIG. 1) may access products (e.g., desktop applications and/or services) through various client applications (e.g., end user consoles). For example, FIG. 1 illustrates an embodiment in which enterprise end users 134 access desktop applications (including those that are managed on behalf of their organizations by the enterprise catalog service) through a desktop application management module 128, and in which end users 134 access server products (including those that are managed on behalf of their organizations by the enterprise catalog service) through a resource stack management service console 130. For example, end users 134 may log into desktop application management module 128 in order to request delivery of, to subscribe to, to unsubscribe from, to install, to uninstall, to launch, or to otherwise manage a particular desktop application (one that may or may not be included in a catalog to which the end user currently has access), or may log into resource stack management service console 130 in order to construct a resource stack instance from a resource stack template (on service provider resources), or request access to a service provided by a resource stack instance that has been constructed (on service provider resources) from a corresponding resource stack template (a service that the end user may or may not currently be authorized to launch). In some embodiments, when requests are received from end users 134 for desktop applications or services that are managed by the enterprise catalog service, they may initiate various workflows of enterprise catalog service platform 108, desktop application fulfillment platform 126 and/or resource stack management service 132 that may or may not result in the end users 134 receiving the requested product access (e.g., depending on various access management policies, constraints, or permissions that apply to the product and/or the end users).

Note that while the example system illustrated in FIG. 1 includes a single service provider management console 106 through which IT administrators 106 interact with the enterprise catalog service platform to perform all IT administrator functions and includes multiple end user consoles (e.g., one for end user functions directed to desktop application management and another for end user function directed to server product management), in other embodiments, a system that implements an enterprise catalog service may include two different management consoles (e.g., one through which desktop applications are managed by IT administrators and another through which server products are managed by IT administrators), rather than a single management console. In still other embodiments, the system may include a single end-user console through which end users manage both desktop applications and server products, rather than two different end-user consoles. In still other embodiments, a system that includes an enterprise catalog service platform, such as that described herein, may be configured to manage and deploy software products other than resource-stack-based server products and desktop applications, and/or may deploy software products for consumption by end users through more, fewer, or different deployment platforms than those illustrated in FIG. 1 as desktop application fulfillment platform 126 and resource stack management service 132. Similarly, in other embodiments, a system that includes an enterprise catalog service platform, such as that described herein, may be configured to ingest software products of types other than resource-stack-based server products and/or desktop applications, and/or may include (or interact with) more, fewer, or different ingestion mechanisms than those illustrated in FIG. 1 as resource stack template editor 104, product discovery service 110, and desktop authoring and ingestion tooling 116.

Although not shown in the example in FIG. 1, the enterprise catalog service may include an interface to (or otherwise work in conjunction with) various data stores or data storage services (e.g., a data storage service implemented by the service provider or an external data storage service). In one embodiment, the documents associated with a product may be stored in an object storage service, and the console (or customer) may be responsible for uploading these documents to system-defined locations through various enterprise catalog service APIs. In this example, the service catalog runtime may pass the location of the documents to the catalog service, and the identity and access management (IAM) role used to upload the documents may be stored by the catalog service. In some embodiments, data about running stacks may be persisted in a database service. In various embodiments, application state data for virtualized desktop applications may be persisted in either an object storage service or a database service.

The systems and methods described herein may be implemented on or by one or more computing systems within a network environment, in different embodiments. An example computer system on which embodiments of the techniques described herein for managing and deploying desktop applications and services through an enterprise catalog service may be implemented is illustrated in FIG. 15. Embodiments of various systems and methods for implementing these techniques are generally described herein in the context of a service provider that provides to clients, via an intermediate network such as the Internet, virtualized resources (e.g., virtualized computing and storage resources), software products, and computing services (including desktop applications and server products) implemented on a provider network of the service provider. FIGS. 1, 2, 4, 5, and 15 (and the corresponding descriptions thereof) illustrate and describe example computing systems and environments in which embodiments of the systems and methods described herein may be implemented, and are not intended to be limiting. In at least some embodiments, at least some of the resources provided to clients of the service provider via the provider network may be virtualized computing resources implemented on multi-tenant hardware that is shared with other client(s) and/or on hardware dedicated to the particular client. Each virtualized computing resource may be referred to as a resource instance. Resource instances may, for example, be rented or leased to clients of the service provider. For example, clients of the service provider may access one or more services of the provider network via application programming interfaces (APIs) to the services to obtain and configure resource instances and to establish and manage virtual network configurations that include the resource instances, for example virtualized private networks.

In some embodiments, the resource instances may, for example, be implemented according to hardware virtualization technology that enables multiple operating systems to run concurrently on a host computer, i.e. as virtual machines (VMs) on the hosts. A hypervisor, or virtual machine monitor (VMM), on a host may present the VMs on the host with a virtual platform and monitors the execution of the VMs. Each VM may be provided with one or more private IP addresses; the VMM on a host may be aware of the private IP addresses of the VMs on the host.

Example Provider Network Environment

This section describes an example provider network environment in which embodiments of the methods described herein may be implemented. However, this example provider network environment is not intended to be limiting. In various embodiments, in such provider network environments, a service provider may host virtualized resource instances on behalf of a customer that can be accessed by end users. For example, end users who are associated with the customer on whose behalf the virtualized resources instances are hosted (e.g., members of the same organization or enterprise) may be able to access the virtualized resources instances using client applications on client devices. In some embodiments, the virtualized resources instances may be configured to implement virtual desktop instances.

In some embodiments, desktop applications that are included in catalogs managed by an enterprise catalog service such as those described herein may be delivered to and/or deployed, installed or executed on virtualized computing resources (e.g., virtual computing resource instances implemented on service provider hardware in a cloud computing environment), rather than on physical client computing devices. In addition, server products that are included in catalogs managed by an enterprise catalog service may be implemented as resource stacks (e.g., stacks of service provider resources) that collectively provide a service. These service provider resources may also include virtualized computing resources, such a virtual computing node instances implemented on service provider hardware in a cloud computing environment. An example service provider network that provides virtualized computing resources for these and other uses is illustrated in FIG. 2 and described below.

FIG. 2 is a block diagram of an example provider network environment, one that provides a storage virtualization service and a hardware virtualization service to clients, according to at least some embodiments. In this example, hardware virtualization service 220 provides multiple computation resources 224 (e.g., VMs) to clients. The computation resources 224 may, for example, be rented or leased to clients of the provider network 200 (e.g., to a client that implements client network 250). As noted in the previous example, in some embodiments, provider network 200 may also provide application virtualization for the benefit of its customers and their end users (e.g., through a packaging service), and may provide on-demand delivery of desktop applications to desktops on physical computing devices and/or virtual desktops through an application fulfillment platform implemented using various resources of service provider network 200. In this example, each computation resource 224 may be provided with one or more private IP addresses. Provider network 200 may be configured to route packets from the private IP addresses of the computation resources 224 to public Internet destinations, and from public Internet sources to the computation resources 224.

Provider network 200 may provide a client network 250, for example coupled to intermediate network 240 via local network 256, the ability to implement virtual computing systems 292 via hardware virtualization service 220 coupled to intermediate network 240 and to provider network 200. In some embodiments, hardware virtualization service 220 may provide one or more APIs 202, for example a web services interface, via which a client network 250 may access functionality provided by the hardware virtualization service 220, for example via a console 294. In at least some embodiments, at the provider network 200, each virtual computing system 292 at client network 250 may correspond to a computation resource 224 that is leased, rented, or otherwise provided to client network 250.

From an instance of a virtual computing system 292 and/or another client device 290 or console 294, the client may access the functionality of storage virtualization service 210, for example via one or more APIs 202, to access data from and store data to a virtual data store 216 provided by the provider network 200. In some embodiments, a virtualized data store gateway (not shown) may be provided at the client network 250 that may locally cache at least some data, for example frequently accessed or critical data, and that may communicate with virtualized data store service 210 via one or more communications channels to upload new or modified data from a local cache so that the primary store of data (virtualized data store 216) is maintained. In at least some embodiments, a user, via a virtual computing system 292 and/or on another client device 290, may mount and access one or more storage volumes 218 of virtual data store 216, each of which appears to the user as local virtualized storage 298.

While not shown in FIG. 2, the virtualization service(s) may also be accessed from resource instances within the provider network 200 via API(s) 202. For example, a client, appliance service provider, or other entity may access a virtualization service from within a respective private network on the provider network 200 via an API 202 to request allocation of one or more resource instances within the private network or within another private network. Note that in some embodiments, the hardware virtualization service 220 may be configured to provide computation resources 224 that have been configured to implement a virtual desktop instance, which may appear to the user as a local desktop (implemented by a virtual computing system 292). Note also that in some embodiments, the computation resources 224 that are made available to the client via hardware virtualization service 220 may include multiple network interfaces. For example, some of them may include one network interface for communicating with various components of client network 250 and another network interface for communicating with computation resources or other network entities on another network that is external to provider network 200 (not shown).

In some embodiments, a service provider network that implements VMs and VMMs may use Internet Protocol (IP) tunneling technology to encapsulate and route client data packets over a network substrate between client resource instances on different hosts within the provider network. The provider network may include a physical network substrate that includes networking devices such as routers, switches, network address translators (NATs), and so on, as well as the physical connections among the devices. The provider network may employ IP tunneling technology to provide an overlay network via which encapsulated packets (that is, client packets that have been tagged with overlay network metadata including but not limited to overlay network address information for routing over the overlay network) may be passed through the network substrate via tunnels or overlay network routes. The IP tunneling technology may provide a mapping and encapsulating system for creating the overlay network on the network substrate, and may provide a separate namespace for the overlay network layer (public IP addresses) and the network substrate layer (private IP addresses). In at least some embodiments, encapsulated packets in the overlay network layer may be checked against a mapping directory to determine what their tunnel substrate target (private IP address) should be. The IP tunneling technology may provide a virtual network topology overlaid on the physical network substrate; the interfaces (e.g., service APIs) that are presented to clients are attached to the overlay network so that when a client resource instance provides an IP address to which packets are to be sent, the IP address is run in virtual space by communicating with a mapping service that can determine where the IP overlay addresses are.

In various embodiments, client resource instances on the hosts may communicate with other client resource instances on the same host or on different hosts according to stateful protocols such as Transmission Control Protocol (TCP) and/or according to stateless protocols such as User Datagram Protocol (UDP). However, the client packets are encapsulated according to an overlay network protocol by the sending VMM and unencapsulated by the receiving VMM. A VMM on a host, upon receiving a client packet (e.g., a TCP or UDP packet) from a client resource instance on the host and targeted at an IP address of another client resource instance, encapsulates or tags the client packet according to an overlay network (or IP tunneling) protocol and sends the encapsulated packet onto the overlay network for delivery. The encapsulated packet may then be routed to another VMM via the overlay network according to the IP tunneling technology. The other VMM strips the overlay network encapsulation from the packet and delivers the client packet (e.g., a TCP or UDP packet) to the appropriate VM on the host that implements the target client resource instance. In other words, in some embodiments, although there may be a single underlying physical network in the service provider computing environment (e.g., the service provider data center), the encapsulations described herein may allow it to appear as if each client application (or each client resource instance on which one or more client applications execute) is running on its own virtual network (e.g., data packets for multiple client applications may be traveling on the same physical network but it may appear as if the traffic directed to each of the client applications is traveling on a private network).

In some embodiments, the overlay network may be a stateless network implemented according to a connectionless (or stateless) IP protocol. In some such embodiments, the sending VMM sends the encapsulated packet onto the overlay network for routing and delivery, but does not receive an acknowledgement (ACK) or other response regarding delivery of the packet. In other embodiments, the VMM may receive an ACK or other response regarding delivery of an encapsulated packet.

In some embodiments, while there are physical computers executing client applications and other processes described herein, the client applications may be running as virtual machines on the physical computers. For example, internal processes of the cloud computing environment that are configured to manage the creation of these virtual machines, to provision resources for these virtual machines, and/or to perform other administrative tasks on behalf of clients and/or their applications (e.g., monitoring resource usage, customer accounting, billing for services, etc.) may execute in a control plane layer (or hypervisor) in the cloud computing environment. By contrast, client applications (e.g., each resource instance that implements an application component) may execute in a data plane layer of the cloud computing environment. Underneath these layers, there may be only one physical network card for each host node (or for multiple host nodes), in some embodiments, but each resource instance may execute as if it has its own network (e.g., a virtual network). In some embodiments, each resource instance may have its own data plane network connection(s), but may make local API calls (e.g., calls to a component on the same node) without needing to rely on these data plane network connections.

In some embodiments, the cloud computing environment may be a multi-tenant environment in which each application (and/or each virtual private network) may have its own namespace. In some embodiments, each client may have its own allocation of network connectivity and/or throughput capacity (bandwidth). For example, the network connectivity and/or throughput capacity in the data plane network may be provisioned (e.g., designated or reserved) for the use of various clients. In various embodiments, a service provider may employ one of the example provider networks described above (or another suitable provider network environment) to implement a hosted desktop service in a cloud computing environment. In such embodiments, a customer may access the provider network in the cloud computing environment to request the instantiation and/or configuration of one or more virtual desktop instances in the cloud, and may then provide access to those virtual desktop instances to one or more end users (e.g., through a client application). For example, an administrator within an organization or enterprise may set up an account with a service provider, may contract with the service provider to set up some number of virtual desktop instances, and (once the virtual desktop instances are set up), may provide credentials for accessing these virtual desktop instances. In this example, once the virtual desktop instances have been set up and credentials have been provided, one or more end users may launch a client application on their a client device (e.g., a computer, tablet device, or other mobile device) and enter the credentials for the virtual desktop instance, after which they may be logged into a virtual desktop environment. Although the virtual desktop environment is implemented by virtualized resource instances in the cloud computing environment, it may appear to the end user as if it were a local desktop and it may operate as if it were an independent computer to which the user is connected. In some embodiments, the virtual desktop environment may provide access to productivity software and other software programs to which the user would typically have access if the user were logged onto a physical computer owned by the organization or enterprise. In at least some embodiments, an application fulfillment platform of the service provider may be configured to provide on-demand delivery of applications (e.g., as virtualized application packages) to virtual desktop instances, as described herein. Note that these applications may or may not be stand-alone applications. For example, in some cases, each of the virtual desktop instances (and/or the applications running thereon) may be part of the active directory framework of the organization or enterprise and may be able to access shared files or other resources on the existing network of the organization or enterprise once the credential presented by the user upon logging into the virtual desktop instance have been authenticated.

In some embodiments, the types of interactions experienced by different users that access the enterprise catalog services (and enterprise catalog service platforms) described herein may be thought of as being divided into multiple phases, where each phase may include tasks that are performed by an IT administrator of a service provider customer organization and/or tasks that are performed by an end user in the customer organization. For example, FIG. 3 illustrates tasks that may be performed by an IT administrator (shown as IT administrator tasks 300) and other tasks that may be performed by an end user (shown as end user tasks 330), according to at least some embodiments. Note, however, that in some embodiments, an IT administrator may be able to perform some or all of the tasks shown as end user tasks 330. In such embodiments, the IT administrator may perform various ones of the end user tasks 330 on behalf of an end user, on their own behalf, or on behalf of the customer organization as a whole. As illustrated in this example, during a product authoring and discovery phase (shown as authoring and discovery phase 302), an IT administrator may create the artifacts for a product to be offered by the enterprise catalog service using appropriate product-specific tools (shown as task 312). In various embodiments, this task may include creating a machine image for a software product, creating a resource stack template for a server product, or packaging a desktop application for delivery to desktops on physical computing devices and/or virtual desktop instances. During this phase, the IT administrator may also discover one or more products that are available to be managed by the enterprise catalog service on behalf of the IT administrator's organization, and may subscribe to one or more of those products on behalf of the end users in the IT administrator's organization (shown as task 319). In various embodiments, during this phase (or during an ingestion phase described below), an IT administrator may (through an administrator or management console of the enterprise catalog service) be able to add additional information for a product listing (e.g., a product listing for a newly authored product or for one that was discovered by the IT administrator), such as a detailed product description, a logo to brand the product, version information and/or tags (which may be used to identify and characterize the product, or may be used in identity and access management policies to allow or deny access to the product or to restrict the operations that can be performed by IAM users, groups, and roles).

As illustrated in FIG. 3, during an ingestion phase (shown as ingestion phase 304), and administrator may upload a product artifact that was created during authoring phase 302. For example, the IT administrator may upload a machine image for a software product, a resource stack template for a server product, or a packaged desktop application to the enterprise catalog service platform (shown as task 314) and publish the machine image, resource stack or packaged desktop application to one or more enterprise catalogs, private catalogs or portfolios (as in task 315). During a portfolio management phase (shown as portfolio management phase 305), the IT administrator may create one or more portfolios (shown as task 316) and may add one or more products that were authored, uploaded, and published by the IT administrator (as in tasks 312, 314, and 315) or that were discovered and subscribed to by the IT administrator (as in task 319) to those portfolios (shown as task 321). During this phase, the IT administrator may also define one or more access management policies and/or constraints to be applied to the product and/or to the portfolios to which the products have been added (as in task 317). For example, in some embodiments, the constraints may include business level input parameters (such as an input parameter specifying the number of users to support or whether certain types of data need to be stored), or may include infrastructure-level input parameters (such as an input parameter specifying the type of virtualized computing resource instance should be used).

As illustrated in this example, during a user discovery phase (shown as user discovery phase 306), an end user within the customer organization may discover one or more products by searching an enterprise-wide catalogs (if the end user has permission to view the enterprise-wide catalog) or their own private catalog (e.g., a logical collection of the products that the end user has permission to discover and/or launch, including any products that are included in portfolios to which the end user has been granted access), and viewing details pages that provide information about the products (as in task 332) and may request access to one or more products (as in task 334). During a fulfillment phase (shown as fulfillment phase 308), the end user may launch one or more of the products in their private catalog (as in task 336) and begin monitoring their state (which may include real-time monitoring of the health of the product and/or tracking costs associated with the provisioning and use of the product (as in task 340). Note that, in some embodiments, IT administrators and/or other decision makers may be required to approve a request to discover or launch a product prior to the end user being allowed to discover and/or launch the requested product. In this phase, the IT administrator may also begin monitoring the state of various products that have been provisioned by (or on behalf of) end users in the customer organization (which may include real-time monitoring the health of the products provided to the end users and/or tracking costs associated with the provisioning and use of the products provided to the end user), as in task 322. For example, in some embodiments, an IT administrator and/or an end user may be able to view a list of products that are currently in use along with their health (e.g., through the administrator/management console or through an end user console). In some embodiments, the product health for a server products built using a resource stack template may be determined according to various alarms that are defined in the template.

As illustrated in FIG. 3, during an on-going management phase (shown as on-going management phase 310), both end users and IT administrators may continue to monitor the health of various products and to track costs associated with the provisioning and use of the products (as in tasks 322 and 340). The IT administrators may also manage those products, as well as any portfolios in which they are contained and/or any constraints or users/permissions that are associated with those products (as in task 318). For example, in some embodiments, managing the products may include enforcing any access management policies and/or constraints that were defined for the products and/or to the enterprise catalogs, private catalogs or portfolios to which the products were published. During this phase, end users may manage their own list of products (as in 338). For example, end users may add or remove products, but may not modify their configurations (e.g., any applicable constraints or permissions). Also note that, in some embodiments, the IT administrator may continue to search for and discover new products, to subscribe to them, and to add them to new or existing portfolios and that the end user may continue to discover and request access to products and/or to launch products to which the end user has been granted access (e.g., by repeating various ones of the tasks illustrated in FIG. 3) during the ongoing management phase 310 (not shown).

Note that in some embodiments, a product (or a particular version of a product) may be deprecated by an IT administrator (e.g., through the administrator/management console of the enterprise catalog service). In such embodiments, when a particular version of a product is deprecated, which may also be referred to as “sunsetting”, a notification may be sent to all end users that have previously provisioned that version of the product. In some embodiments, end users who previously provisioned (and are currently using) a product version that has been (or is about to be) sunsetted may continue to use that product version unless, for example, an IT administrator determines that it is a security risk and revokes access to that product version for all end users. However, a product version that has been (or is about to be) sunsetted may not be available to any other end users (e.g., end users who have not previously provisioned that product and/or are not currently using it). In some embodiments, once an end user stops using a product version that has been (or is about to be) sunsetted, the end user may no longer have access to that product version. Note also that new product versions may be created in the same way that new products are created (e.g., through the administrator/management console of the enterprise catalog service). In some embodiments, when a new version of a product is published to a catalog or portfolio, a notification may be sent to all users that have provisioned previous versions of the product. Creating a new version of a product may not affect any existing versions of the product that are currently in use.

One embodiment of a service provider system that is configured to provide on-demand delivery of applications (e.g., desktop applications) to computing resource instances of its customers' end users is illustrated by the block diagram in FIG. 4. As illustrated in this example, the system, implemented on service provider network 430, may include an application fulfillment platform (shown as desktop application fulfillment platform 420). The application fulfillment platform may include an interface mechanism (shown as service provider system console 422) through which an IT administrator of a service provider customer (e.g., a business, enterprise, or organization that receives computing services, storage services, and/or access to second or third party applications from the service provider) can manage the fulfillment of various applications to their end users (e.g., employees or members of the same business, enterprise, or organization). For example, the IT administrator may log into desktop application fulfillment platform 420 (e.g., through a browser or a dedicated client-side application) to access service provider system console 422. The IT administrator may then provide input (e.g., requests for service entered in a graphical user interface of service provider system console 422) in order to create a catalog of applications to be provisioned for the use of their end users, to assign applications to particular end users or user groups, or to generate, obtain, or view usage reports for the applications in the catalog by their end users.

As illustrated in this example, desktop application fulfillment platform 420 may include multiple fulfillment platform control plane services 426, various ones of which may be invoked in response to the inputs received from the IT administrator. For example, in response to inputs specifying the addition of an application to a catalog and the assigning of the application to one or more users, a “create fulfillment” workflow may be initiated, which may include operations performed by a fulfillment service, an entitlement service, a delivery service, a packaging service, a device identifier service, and/or a proxy service. As illustrated at 424, in this example, applications may be delivered to end users as application binaries (e.g., desktop applications that have been prepared for physical installation on an end user's computing resource instance) and/or as virtualized application packages. For example, in some embodiments, the service provider may (e.g., when ingesting desktop applications for the benefit of its customers and their end users) transform desktop applications into virtualized application packages to be delivered to end users' computing resource instances, and those virtualized application packages may be executed on those computing resource instances without the end user having to install the desktop applications themselves on those computing resource instances.

In some embodiments, an application delivery agent (such as desktop application delivery agent 436 illustrated in FIG. 4) and a desktop application management module (such as desktop application management module 432) may be installed on the end user's computing resources instance 438. In various embodiments, computing resource instance 438 may be a physical computing device (e.g., a desktop or laptop computer, a tablet computing device, or a smart phone) or may be a virtualized computing resource instance (e.g., one that implements a virtual desktop instance). Desktop application delivery agent 436 (which may be a client component of desktop application fulfillment platform 420) may be configured to communicate with various fulfillment platform control place services 426 in order to fulfill requests to subscribe to, install, and/or execute applications selected through desktop application management module 432 or through another user interface mechanism (e.g., application icon 440 on desktop 434 or a start menu item). In other words, desktop application management module 432 is an application that may be installed on the end user's computing resource instance 438 to allow the end user to interact with desktop application fulfillment platform 420 through desktop application delivery agent 436. In some embodiments, desktop application delivery agent 436 may include a runtime engine component that is configured to execute the instructions of a virtualized application package 424 that is delivered (e.g., using demand paging) for a selected application. The functionality of an application delivery agent is described in more detail below, according to at least some embodiments.

As illustrated in FIG. 4, the service provider network may include physical and/or virtualized computing resource instances (e.g., computation resource instances and/or storage resource instances) that may be provisioned on behalf of the business, enterprise, or organization (and its end users). In some embodiments, these computing resources instances (shown as computing resource instances 428 on service provider network 430) may be configured to implement a remote computing application that allows end users to access applications executing on computing resource instances 428 as if they were installed and executing locally on their machine. For example, in some embodiments, one or more of these computing resources instances 428 may be configured to implement a virtual desktop instance (which may serve as the end user's computing resource instance 438) on which a desktop application delivery agent 436 and a desktop application management module 432 are installed. In such embodiments, desktop 434 in FIG. 4 may represent a view presented by the virtual desktop instance and may appear to the end user as if it were a desktop on the end user's local (physical) computing device. In some embodiments, service provider network 430 may also include storage resources outside of desktop application fulfillment platform 420 (which may be managed by a storage service implemented within service provider network 430) that are configured to store data utilized by desktop application fulfillment platform 420 (not shown). In various embodiments, application binaries, virtualized application packages, various tables that store information about applications and collections thereof, application state data, or other information used to provide on-demand delivery of desktop applications to end users may be stored outside of desktop application fulfillment platform 420 instead of, or in addition to, within desktop application fulfillment platform 420.

As illustrated in this example, desktop application management module 432 (through which the end user may select applications for installation or execution) may execute on the end user's computing resource instance 438, and a graphical user interface of desktop application management module 432 may be displayed on desktop 434. For example, this interface may present a list of applications for selection by the end user (e.g., in order to subscribe to, install, and/or execute an application). In addition, a shortcut or icon for an application (shown as element 440 in FIG. 4) may be displayed on desktop 434 and may be selected in order to launch the corresponding application (e.g., desktop application management module 432, or one of the applications delivered for execution on computing resource instance 438 in response to its selection, by the end user, within desktop application management module 432).

As described above, in some embodiments, an enterprise catalog service may operate in conjunction with (or may provide an interface to) a resource stack management service (such as resource stack management service 132 illustrated in FIG. 1). This service may help service provider customers (e.g., administrators and/or end users) model and set up service provider resources on which server products may run within the service provider network. Through a resource stack management service console (such as resource stack management service console 130), administrators may create a resource stack template that describes all of the service provider resources required for a particular tasks or server product (such as virtualized computing resource instances and/or database instances). Once the resource stack template is created, the resource stack management service may take care of provisioning and configuring those resources for the customer. Other resources that may be defined in a resource stack template include an auto-scaling component, a load balancer, or an additional storage service instance. Once a resource stack is no longer needed, it may be deleted, which deletes all the resources in the stack. In addition, a resource stack template may be modified by editing the definition or by creating a new version of the template that includes a different definition. For example, a resource stack template may be modified in order to include a higher performing computing resource instance type or to add additional storage resources.

As previously noted, an enterprise catalog service may operate in conjunction with (or provide an interface to) a resources stack template tool that may be accessed by an IT administrator or end user in a customer organization (e.g., through an administrator/management console or through an end user console such as resource stack management service console 130) to create a collection of interdependent resources that form a resource stack. The resource stack management service, enterprise catalog service, or another service provider service or platform may maintain and manage a catalog of resources that can be included in a resource stack.

In one embodiment, an IT administrator or end user in a customer organization may create, select or otherwise specify a template that defines a resource stack. The resource stack may comprise resources available from the service provider. The resource stack template may also include information about how the resources are to be linked together in the resource stack and how the resources are to be configured. When a resource stack is created, it may be created in accordance with the information contained in the resource stack template. For example, creating a server product from a resource stack template may include determining the dependencies between the resources and an order in which the resources should be instantiated (e.g., provisioned using service provider resources), dependent on the resource stack template. After successful provisioning and integration of the resources, the resource stack may be enabled for use.

In one example, at a newspaper company, in order to enable all of the reporters to have their own blogs, an IT administrator may make them all end users under the organization's service provider account. The IT administrator may access the enterprise catalog service (e.g., through an administrator/management console), through which the IT administrator may subscribe to a blog publishing package (server product), create a catalog or portfolio, add the blog publishing package to the catalog/portfolio, and then grant access the blog publishing package to each of the end users (reporters). In this example, when the end users (reporters) access the catalog/portfolio (e.g., through the end user console), they would see the blog publishing package as an application that they can deploy. For example, an end user may select the blog publishing package (e.g., as an icon or shortcut), in response to which the resource stack management service may deploy the machine image for the blog publishing package (which may also include a database instance or other storage resource instance in addition to a computing resource instance). Once the blog publishing package has been deployed, the end user may begin using it to create their own blogs (blogs over which they have control). In some embodiments, the IT administrator may constrain the use of the blog publishing package, e.g., only allowing development on a computing resource instance of a certain size (e.g., a small instance with limited computing power), rather than on a larger computing resource instance (even if those are available to the newspaper company through their service agreement with the service provider). In another example, the IT administrator may be able to limit the amount of storage that each end user can consume (e.g., 10 Gb per end user).

In this example, for every blog that is launched by one of the end users (reporters), the enterprise catalog system may generate billing information for the IT administrator. For example, the IT administrator may be billed monthly for whatever number of blogs were launched during that month and for the use of the underlying service provider resources (e.g., computing resource instances and storage resource instances). In some embodiments, the service provider may collect usage fees from the customer organization and then pass along payments to any third party vendors from whom an application or server product was sourced. For example, in one embodiment, the service provider may keep fees associated with the hardware resources and/or virtualized computing resource instances on which the server product (e.g., a resource stack application) runs (i.e., fees for the use of the service provider's infrastructure), and a percentage of the fees associate with the application, passing the bulk of the fees collected for use of the server product (e.g., by one or more organizations and their end users) to the appropriate third party vendor(s), e.g., monthly or on any other suitable billing schedule. Note that, in some embodiments of the systems and services described herein, for software products sourced by third party vendors, there may be flexibility in the way that any applicable taxes on the software products or services are collected and paid (e.g., allowing collection by the service provider and/or payment to the appropriate taxing authority by the third party vendor, the IT administrator, or the service provider). There may also be some flexibility in which entity gets to set the prices charged to the customer for software products that are sourced by third party vendors (e.g., the service provider or third party vendor), with options for the service provider to bundle multiple software products together from different vendors and offer them to customers with discounted pricing.

In some embodiments, in order for the enterprise catalog service (or an underlying enterprise catalog service platform) to manage the ingestion, configuration, deployment, and on-going management of different types of software products (which are sourced from different independent software vendors or other entities) for end users who consume them on a variety of deployment platforms, the enterprise catalog service may maintain metadata of several different types for each of the software products that are available for deployment through the service, and the types of metadata maintained for the software products may vary by product type, by target system, or by source (e.g., by vendor). For example, for each of the software products, the enterprise catalog service may be configured to store (and subsequently use, e.g., for display purposes, for deployment purposes, or for determining pricing) the same combination of metadata elements or a different combination of metadata elements, which may include metadata elements reflecting any or all of the following types of information: offer information, a license type, subscription or licensing terms, a product format, resource requirements, an indication of the vendor or other sourcing entity, entitlement information, information indicating any constraints that are associated with a product, portfolio, or user, access management information, or information indicating one or more portfolios in which the product is included). In some embodiments, the metadata maintained for each of the software products may be dependent on the source of the product or on other characteristics of the product. For example, offer information (which may include a pricing type, a price, and/or taxing information for a specified product) may be maintained for products obtained from third party vendors, but not for the customer organization's own line-of-business products. In some embodiments, the metadata may include multiple offers for similar products from different sources, or one more than one offer for a single product, but not all of the offers may be discoverable by administrators or end users. In some embodiments, the metadata maintained for each of the software products may be filtered or sorted so that only products that an administrator or end user has permission to view/discover are presented and/or only a particular subset of the metadata maintained for those products is presented. For example, the enterprise catalog service may be configured to present only the technical details or business information that an administrator or end user needs to know and/or has permission to view. In one example, there may be three different offers for a particular software product: a three day free trial offer, a regular offer, and a volume discount offer, but the information that is presented to an administrator or end user may be sorted or filtered so that only the offers that the administrator or end user is eligible to receive can be viewed by the administrator or end user. In some embodiments, the enterprise catalog service may be configured to filter or sort the metadata that is maintained for various software products in order to present similar information to an administrator or end user (e.g., for use in comparing the products), even if the metadata maintained for the products is not of exactly the same type or format.

In some embodiments, the enterprise catalog service may be configured to take specific actions in response to changes to the specific metadata elements that are maintained for a particular software product. For example, if an offer for a software product changes, the service may be configured to apply the change immediately or after a delay, depending on the change. In this example, if the price goes down (e.g., if a new offer is available for the product that includes a lower price), the service may modify the offer that is received by an existing customer right away (or at the end of the next billing cycle). However, if the price goes up (e.g., if a current offer for the product is replaced by an offer in which the price is higher), the service may allow an existing customer to use the current offer for some period of time (e.g., 90 days) before notifying the customer of the change and/or modifying the offer through which the customer receives the product. In some embodiments, in addition to maintaining (and acting upon) different types of metadata for different software products, the enterprise catalog service may be configured to apply different packaging and/or software integration processes or mechanisms when ingesting or deploying products of different types or from different sources, which may include translating or otherwise transforming the products (or the product packages in which they are delivered) into a format that is suitable for ingestion by the enterprise catalog service from different vendors or for deployment to different or end user systems (e.g., systems that employ different hardware resources or operating systems).

FIG. 5 illustrates the use of a resource stack template to build and deploy a server product, according to at least some embodiments. As illustrated in this example, a client of a service provider system 530 may provide a resource stack template 510 that defines the resources 514 that will be used to execute a server application (e.g., a server product) on behalf of an end user of a service provider customer and a set of metadata 512 for the resource stack. For example, the resources may include one or more compute node instance (or other modules) that will be used to execute the server application, a set of database instances that will store the data processed by the server, load balancers for distributing request traffic or other resources, and the metadata may include configuration files (which may contain the identities and/or setting for various resources of the resource stack), connectivity/dependencies, user identity and/or permissions information, alarms, tags, or other information. In some embodiments, the resource stack template may be received from an IT administrator of a service provider customer (e.g., through a service provider management console such as service provider management console 106 illustrated in FIG. 1) or from an end user (e.g., through a resource stack management service console such as resource stack management service console 130), either of which may expose a resource stack template authoring tool with which the resource stack template was created.

In some embodiments, in response to receiving the resource stack template 510, the service provider system 530 (or, more specifically, a resource stack management service 520 that is implemented on the service provider network) may parse the template and build the stack of resources 514 that are defined in the template 510 and that will be used to execute the server application (shown as resource stack 540). For example, in some embodiments, the resource stack management service 520 may include a resource provisioning system that is configured to instantiate the resources defined in the template 510 to create resource stack 540. In some embodiments, building the resource stack 540 may include instantiating at least one computing resource instance (e.g., compute node 542) that will execute the server application 544 and manage its runtime environment, and may include one or more other stack resources (shown as stack resources 546). The compute node 542 may be a virtualized computing resource instance that has a predefined computing capacity and/or memory capacity. In some embodiments, the compute node 542 may be loaded with an operating system, configuration files, or other resources that are pre-installed on the compute node 542 when it is instantiated. In some embodiments, the computing resource instance may include an initialization script that will be used to apply the metadata 512 defined in the resource stack template 510 to the compute node 542 and/or application 544 when the application is launched on resource stack 540 by end user 550 (e.g., through its selection within a GUI of a resource stack management service console such as resource stack management service console 130 illustrated in FIG. 1). Note that, in some embodiments, service provider system 530 may also include other services that interact with the resource stack (e.g., an identity management service or other security/authorization services).

Administrator Tasks

As previously noted and described in more detail below, in order to manage the delivery of software products to end users, an IT administrator of a business, enterprise, or other organization may be able to perform a variety of different actions through an administrator console of an application fulfillment platform (such as service provider management console 106 in FIG. 1 or service provider system console 422 in FIG. 4), many of which fall into one of the following three broad categories:

-   -   1) Building a catalog for the organization, where the catalog is         a collection of software products that may include any of the         following product types:         -   the organization's own line-of-business (e.g., custom)             applications         -   desktop applications or server products for which the             organization has purchased licenses, including             enterprise-wide licenses (e.g., products that may be             included in the catalog under a “bring your own license”             model)         -   desktop applications or server products purchased or leased             from the service provider (e.g., products that were             developed by the service provider or that were purchased or             leased by the service provider for the benefit of its             customers)     -   2) Assigning particular software products to specific end users         and/or user groups in the same organization     -   3) Generating, obtaining, and/or viewing reports indicating the         usage of the software products that are provided through an         application fulfillment platform or resource stack management         service to end users in the same organization

As noted above, the systems and methods described herein for implementing an application fulfillment platform may, in various embodiments, allow large enterprises to create and manage catalogs (or portfolios) of software applications and computation services, including server applications that execute in a cloud computing environment and desktop applications that execute on physical computing devices, virtualized computing resource instances, and virtual desktop instances. These systems may allow service provider customers (e.g., enterprises) to ingest their own line-of-business applications (e.g., server applications and/or desktop applications) into the catalogs (or portfolios), through which they may be made available for use by their end users. In some embodiments, an IT administrator of a service provider customer may interact with the service provider system through an administrator console to assign and provision applications to various end users and/or to define constraints on the use of those applications. This may include invoking operations or workflows of a resource stack management service (in the case of server applications) or an application fulfillment platform (in the case of desktop applications to be executed on an end user's physical computing device or virtual desktop instance).

In some embodiments, a company that wishes to use one or more applications for software trials, short-term needs or low-volume needs may obtain access to those applications through an “applications on-demand” model that is managed through the application fulfillment platform (thus, taking advantage of the more favorable terms that may be received by the service provider as a higher volume customer of the application vendor). In some embodiments, the company may obtain access to server products under a similar “services on-demand” model that is managed through the resource stack management service.

As noted above, in some embodiments, desktop applications (e.g., individual applications and/or collections of applications) and/or server products may be assigned by an IT administrator to individual users and/or user groups in an active directory to allow access to those applications. For example, an active directory of an enterprise (e.g., a company that is a customer of a service provider) may sit at the center of its resource management processes. Resources (e.g., users, computers, printers, or other corporate resources, each of which may have its own identifier) may be connected to the active directory, and an IT administrator at the company may give users access to particular ones of the resources. In some embodiments, an IT administrator may create a cloud-based active directory for the enterprise. In other embodiments, connections may be made from a virtual desktop instance to an active directory on an enterprise computer system.

In some embodiments, the IT administrator may, through an administrator console (e.g., a service provider system console) assign particular desktop applications and/or server products to specified users (and/or user groups) by selecting one or more users and/or user groups in its active directory from a display of the active directory (or through another interface into the active directory). For example, the IT administrator may be able to assign applications (e.g., one or more desktop applications, such as an office productivity suite, a data analysis application and/or a browser application) or server products (such as a website design package or blog publishing package) to the selected users and/or user groups (e.g., groups of users that are defined in the active directory, such as a “development team” or “legal team”). In another example, an IT administrator may wish to provision a desktop application (e.g., a word processing application) to user1, user2, and group1 in an active directory. The actions taken in order to carry out that fulfillment may depend on the type of application. In this example, since the application is a desktop application that is available through an application fulfillment platform, the IT administrator may (e.g., through an administrator console) assign the desktop application to user1, user2, and group1, and fulfilling the intended state for user1, user2, and group1 may include invoking various workflows of the application fulfillment platform. In another example, if a server product (e.g., a server-side application that executes on a pre-defined stack of a service provider resources on behalf of an end user and returns a response) is to be provisioned to user1, user2 and group1, fulfilling the server product may include invoking workflow of the resource stack management service.

In some embodiments, the IT administrator may, through an administrator console (e.g., a service provider system console) also be able to apply various constraints on the use of selected desktop applications and/or server products by end users or user groups to which these products are assigned (either individually, or collectively). For example, in various embodiments, the constraints that may be applied by the IT administrator may be broadly categorized as being one of the following four types: environmental constraints (which may restrict the region in which a product can be provisioned), input parameter constraints (which may restrict the set of valid values for input parameters that can be entered when a software product is provisioned or updated), quotas (which may allow the administrator to control the number of concurrent deployments of a given software product) and billing constraints (which may allow the administrator to control spending limits on an product by product basis). In some embodiments, constraints may applied at multiple levels (e.g., per product per user or user group, per product catalog or portfolio, or at one level for some catalogs/portfolios or users and at another level for other catalogs/portfolios or users. For example, when constraints are applied to a catalog or portfolio, all users who have access to that portfolio will have same constraints and permissions on the products in the catalog or portfolio by default, but there may also be some specific constraints for particular product/user combinations. For example, one user may have to select a radio button element of a GUI presented by an end user console in order to install a particular product. For other users, the product may automatically appears on their system under an “autodeploy” setting selected for the user. In this example, required software products may be automatically installed by default, while optional products may be “user initiated”. In another example, a product level constraint may specify that no one customer or user can install more than 10 copies of a particular product (e.g., because of the number of licenses the organization has purchased).

In yet another example, the collection of three applications described above may be assigned to three active directory users, one of which may represent a user group. In this example, constraints may be set indicating that user1 should use a particular version of application) (e.g., an office productivity suite) and should not have access to any updated versions of application); that user2 should use a particular version of application2 (e.g., a data analysis application) that is compatible with a particular operating system revision and should not have access to any updated versions of application2; and that user3 (which may represent a group of active directory users) may have access to application3 (e.g., a browser application) that should always be kept current (e.g., with updates applied automatically, when available).

As previously noted, an administrator may define rules that limit the parameter values that a user can enter when they use a product. These rules define input parameter constraints. Other constraints may be attached to a catalog or portfolio of software products, and may apply to all products in the catalog/portfolio or to individual products within the catalog/portfolio. In some embodiments, constraints may be associated with IAM users, groups or roles allowing an IT administrator to restrict the service provider resources that can be created by specific end users or groups of users. The constraints that are enforced when provisioning a product or updating a product that is being used may be evaluated by combining all of the constraints from the catalog/portfolio or product, and the intersection of all the constraints may be enforced when the user is provisioning the product. In some embodiments, the most restrictive set of constraints may be applied when different sets of constraints have been selected for a given user or software product. For example, if a product may allow all computing resource instances to be launched, and a catalog or portfolio that contains the software product may have a constraint that allows all non-GPU computing resource instances to be used, but the user has a constraint that only allows tiny and extra small computing resource instances to be launched, then the effective constraint used when that user provisions that product from that portfolio will be the constraint that only allows tiny and extra small computing resource instances to be launched.

As noted above, in some embodiments, the IT administrator may, through an administrator console (e.g., a service provider system console) be able to generate, obtain, and/or view reports indicating the usage of the desktop applications and/or server products that are provided through the service to their end users. For example, these reports may indicate how many (and/or which) users are using each software product, how many (and/or which) users are using each version (e.g., the latest version or an outdated version) of a particular software product, the duration for which each software product is used by one or more users, and/or other usage information. The information in these reports may be used by the IT administrator to determine which of several available licensing models (e.g., on-demand subscriptions/leases using licenses obtained by the service provider, enterprise licenses obtained directly from the software vendors but managed by the service provider, etc.) may be most suitable for the software being used by their organization.

FIGS. 6A-6E illustrate examples of the information presented through a service provider console of an enterprise catalog service, according to at least some embodiments. For example, FIG. 6A illustrates information presented by a graphical user interface (GUI) 600 for a service provider console of an enterprise catalog service to an IT administrator or buyer for a service provider customer. Note that in some embodiments, the IT administrator or buyer may access the service provider console through a browser application (e.g., as a web page). As illustrated in FIGS. 6A-6E, GUI 600 may present different views in order for the IT administrator or buyer to manage desktop application, server-side products, or product subscriptions (which may include product licenses), to generate and/or view reports (e.g., desktop application usage and/or server product deployment reports), to create portfolio, to add products to portfolios, to search for products, and to view (and, in some cases, take action in response to) notifications. More specifically, FIG. 6A illustrates information that may be presented to an IT administrator or buyer who wishes to discover and select desktop applications to be ingested by the enterprise catalog service (e.g., in response to selection of the “desktop applications” tab near the top of the display).

The information presented in this example includes, in one portion of the display, a list of desktop applications, along with the vendors that developed or published the applications and/or from which they were obtained, and user interface elements that may be selected if the IT administrator or buyer would like to view more information about a particular one of the listed applications. In this example, the IT administrator or buyer has indicated a desire for more information about database application F, version 2.3, from vendor ABC. Another portion of the display includes information about options for filtering the list of applications that are presented. In this example, the IT administrator or buyer has selected filtering options to limit the list of applications to productivity applications that are priced according to a monthly fee schedule, and that are compatible with an operation system A version 4.1 (i.e., the latest available version of OS A). This portion of the display also includes an option to view line-of-business applications (e.g., desktop applications that were developed and/or published by the service provider customer itself), and an option to ingest an application (e.g., a line-of-business application).

FIG. 6B illustrates information that may be presented by GUI 600 to an IT administrator or buyer who wishes to discover and select server products (or resource stack templates thereof) to be ingested by the enterprise catalog service (e.g., in response to selection of the “server products” tab near the top of the display). The information presented in this example includes, in one portion of the display, a list of server products, along with the vendors that developed or published the server products (or their resource stack templates) and/or from which they were obtained, and user interface elements that may be selected if the IT administrator or buyer would like to view more information about a particular one of the listed server products. In this example, the IT administrator or buyer has indicated a desire for more information about website design package A, version 3, from vendor ABC. As in FIG. 6A, another portion of the display includes information about options for filtering the list of server products that are presented. In this example, the IT administrator or buyer has selected filtering options to limit the list of server products to web publishing products that are priced according to a monthly fee schedule, and that are compatible with an operation system A version 4.1 (i.e., the latest available version of OS A). This portion of the display also includes an option to view line-of-business services (e.g., server products that were developed by the service provider customer itself), and an option to ingest a server product (e.g., a resource stack template for a line-of-business service). In this example, after selecting website design package A, version 3, the IT administrator or buyer may opt to “Select and Continue”, as shown near the bottom right corner of the display.

FIG. 6C illustrates information about website design package A, version 3 that is presented by GUI 600 in response to its selection on the previous display. In this example, the information presented includes pricing information for website design package A, version 3, including software charges and service provider resource/infrastructure charges that are associated with the selected server product. Note that, as illustrated by the boxes representing pull-down menus for three of the elements in the “Instance type” column, the IT administrator or buyer may be able to specify one of several available instance types for at least some of the resources associated with the selected server product (each combination of which may represent a different offer) Other information that may be selected for viewing from this display includes an overview of the product, technical details, ratings and reviews. In this example, the IT administrator or buyer has selected an option to accept the presented terms (e.g., the presented pricing) for the selected offer and continue, as shown near the bottom right corner of the display. In other words, the IT administrator has selected an offer for a product to be ingested into a catalog of products that is owned by the IT administrator and from which individual products may subsequently be added to one or more portfolios (following their ingestion), which may include subscribing to the product on behalf of end users in the service provider customer organization. In some embodiments, accepting the presented pricing terms may trigger the invocation of a workflow to ingest and package the selected server product for inclusion in a default catalog for the service provider customer (or for the IT administrator) and/or for inclusion in one or more private catalogs or portfolios.

FIG. 6D illustrates information presented by GUI 600 on behalf of the enterprise catalog service. In this example, the IT administrator or buyer has selected an option “create portfolio.” Other options available from this display include “ingest products” and “assign products to users”, each of which may present information that is different than the information depicted in FIG. 6D. As illustrated in this example, in order to create a new portfolio, the IT administrator or buyer may enter a portfolio name, a description of the portfolio, and (optionally) one or more tags for the portfolio into text boxes of GUI 600, and may specify the portfolio type using a radio button user interface element. For example, the IT administrator or buyer may indicate whether the new portfolio will include a collection of desktop applications or a collection of server products. In some embodiments, both desktop applications and server products may be included in a single portfolio.

In this example, the IT administrator or buyer has indicated that the new portfolio, which has been named “Bob's team”, will include only server products, and that it includes “analysis SW for project XYZ”, which, apparently, will be used by end users in the customer organization that are members of Bob's team. As illustrated in this example, in some embodiments, the IT administrator or buyer may also be able to use radio button user interface elements to select from among various portfolio-level configuration parameter settings and/or policy options for the new portfolio (which may include default polices that may be applied to the products included in the new portfolio), e.g., settings specifying that the prices of server products will be displayed (e.g., when the product names are displayed or in search results), that minor revisions to products in the portfolio (but not major revisions) should be applied automatically (with notifications received for major revisions), and that the default installation policy for the server products in the portfolio (which may be overridden on a product basis, in some embodiments) is that that the products are optional. After making these selections, the IT administrator or buyer has opted to “Continue” as shown near the bottom right corner of the display. Note that in other embodiments, the IT administrator may not be able to select portfolio-level configuration parameter settings or policy options for the new portfolio (nor any default polices that will be applied to the products included in the new portfolio). For example, in some embodiments, these types of selections may be made on a product basis, rather than on a portfolio basis. In still other embodiments, these and/or other selections may be made through a separate operation, rather than as part of the operation to create the portfolio.

FIG. 6E also illustrates information presented by GUI 600 on behalf of the enterprise catalog service. In this example, the IT administrator or buyer has selected an option to add products to a portfolio (more specifically, to add “server products” to the recently created portfolio that is named for “Bob's team”, as indicated by the selection of the corresponding tab near the top of the display). Other options available from this display include “desktop applications” and “subscriptions”, each of which may present information that is similar to, but not necessarily the same as, the information depicted in FIG. 6E for adding desktop applications and subscriptions to a portfolio, respectively.

The information presented in this example includes, in one portion of the display, a list of server products, along with the vendors that developed or published the server products (or their resource stack templates) and/or from which they were obtained, pricing information, and indications of the last time the products were updated. In this example, the IT administrator or buyer has selected website design package A, version 3, from vendor ABC. As in FIG. 6A, another portion of the display includes information about options for filtering the list of server products that are presented, and the IT administrator or buyer has selected filtering options to limit the list of server products to web publishing products that are priced according to a monthly fee schedule, and that are compatible with an operation system A version 4.1 (i.e., the latest available version of OS A). As in FIG. 6A, this portion of the display also includes an option to view line-of-business services (e.g., server products that were developed by the service provider customer itself). In this example, after selecting website design package A, version 3, the IT administrator or buyer may opt to “Select and Continue”, as shown near the bottom right corner of the display. In some embodiments, selecting this product and continuing may initiate the addition of the selected product to the portfolio (in this case, the recently created portfolio that is named for “Bob's team”), as described herein. Note that the graphical user interface 600 for a service provider console of an enterprise catalog service may, in other embodiments, display more, fewer, or different elements than those illustrated in the examples shown in FIGS. 6A-6E. In addition, the user interface elements included in a graphical user interface for a service provider console of an enterprise catalog service may, in other embodiments, take different forms (e.g., as menu items, icons, radio buttons, text boxes, check boxes, or other user interface element types) and/or may be arranged in a different order or in different positions within the GUI than the order or positions in which they are arranged in FIGS. 6A-6E.

As previously noted, the enterprise catalog services described herein support the concept of a portfolio, where a portfolio acts as a container for software products. At any given time, a portfolio can have zero or more products in it, and a software product may be in multiple portfolios. As described above, administrators may create portfolios, add products to them, and, using IAM permissions, publish portfolios to make them visible to users. Users may have access to any number of portfolios, as specified by their administrators. By default, a user with access to a portfolio may have access to all of the products that it contains. In some embodiments, portfolios can be shared across service provider accounts (e.g., exported and/or imported by their administrators, assuming they have approval and/or permissions to do so). In various embodiments, access management policies (and/or usage constraints) may be applied to an entire portfolio, or to an individual product or product type. The portfolios (the grouping) and the access management policies and/or groups of constrains that are applied to the grouping may be mutable and may be shared between accounts, in some embodiments. In some embodiments, the smallest atomic unit of software resources may be an application, and a portfolio may represent a logical collection of applications.

In various embodiments, actions that can be taken on a portfolio may include one or more of the following:

1. Create

2. Read

3. Search/filter

4. Update (add/remove Products, update policy)

5. Share

6. Delete

As described above, in some embodiments, the IT administrator may (e.g., through a service provider console for IT administrators) assign resources (in this case, applications) directly to individual users or user groups. In other embodiments, rather than assigning each individual application to various users and/or user groups, a collection of applications (e.g., a logical collection of applications that are included in a defined portfolio) may be assigned to users or user groups. For example, a portfolio may be created for the use of a legal team that includes a set of office productivity applications, legal software, and compliance management software, and the portfolio may (collectively) be assigned to the active directory user group “legal team”. In this example, in addition to (or stead of) assigning the portfolio to the legal team (on whose behalf it was created), the portfolio may be assigned to one or more other active directory users and/or user groups with similar software requirements, roles, and/or permissions to access the software included in the portfolio.

In some embodiments, an IT administrator may select one of two or more options indicating when updates are applied to users of a particular portfolio. In such embodiments, if a new employee joins a company, the IT administrator may assign them to the portfolio, and the required software products may be automatically delivered to their physical computing device or virtual desktop instance. If an IT administrator adds a product to a portfolio or removes a product from a portfolio, the portfolio may be updated automatically. In some embodiments, the IT administrator may also be able to set the update window for minor updates, major updates, and hot fixes for the products in a portfolio at the portfolio level. This setting may apply to all products in the portfolio. In some embodiments, the IT administrator can also choose whether or not to make the entire third party product catalog available for a user to view, after which the end user may submit a request to access one or more of the software products discovered in this manner.

In some embodiments, at the product level, the IT administrator can designate a product as being required or optional, and can set a maximum number of installs (deployments) for a product. For example, the IT administrator can define the maximum number of times that a given product can be provisioned from a portfolio, and the enterprise catalog service may enforce this constraint, ensuring that the limit is not exceeded. Required products are automatically installed, but end users may choose whether or not to install optional products.

In some embodiments the IT administrator may receive new product notifications as a weekly digest and may also see lists of new products from within the administrator/management console of the enterprise catalog services described herein. In some embodiments, all products that were recently released (e.g., released within the last seven days) may be highlighted a displayed list of products as being “New”.

In some embodiments, an IT administrator may be able to get detailed reports on two different levels. For example, the IT administrator may receive an enterprise report, which includes a list of all software products that includes, for each product, the product name, the vendor, license type (e.g., subscription), installs (e.g., the number of deployments), the number of out-of-date installs, a cost per install per month, the percentage of installations that are up-to-date, the total spend, the number of users, the top rated products, or the number of portfolios. The second report may reflect usage at the portfolio level, and may include, for each product in the portfolio, information indicating the portfolio name, the number of products in the portfolio, the assigned users, the cost per user per month, and the total cost. Some example portfolios may include an HR portfolio, an engineering portfolio, a finance portfolio, a shared services portfolio, or a customer service portfolio.

One embodiment of a method for managing desktop applications through an enterprise catalog service (such a service implemented by the system illustrated in FIG. 1) is illustrated by the flow diagram in FIG. 7. As illustrated at 710, in this example, the method may include an IT administrator of a service customer organization selecting, through a product discovery service interface that presents information about desktop applications that are sourced by third parties through the product discovery service, one or more desktop applications to be purchased or licensed from a third party (e.g., a software vendor) on behalf of service provider customers. In various embodiments, the selection may be dependent on technical features (e.g., capabilities of the application and/or resources required to execute the application), a pricing breakdown, the applicable terms of use (e.g., licensing or subscription terms), ratings and/or reviews, the availability of support from the vendor and/or other information. The method may include ingesting and/or packaging the selected third party desktop application(s) into a product catalog owned by the IT administrator for management through the enterprise catalog service. For example, in some embodiments, the IT administrator may discover and select one or more desktop applications (e.g., applications that were developed and/or published by the service provider and/or by third parties) to be offered to their customers and may package and/or publish the desktop applications as isolated virtualized applications (e.g., each packaged in its own container) for subsequent delivery to end users through an application fulfillment platform. As illustrated at 720, in this example, in some embodiments, the method may include ingesting into the IT administrator's product catalog, one or more custom desktop applications (e.g., a line-of-business applications) that were developed by the customer organization, e.g., using a desktop application authoring and ingestion component (such as desktop application authoring and ingestion tooling 116 in FIG. 1) that is exposed to the IT administrator through the service provider management console.

As illustrated in this example, the method may include receiving, through the service provider management console, input indicating the selection of one or more previously ingested and packaged desktop applications to be included in a portfolio for subsequent access by particular end users of a service provider customer (as in 730). For example, in various embodiments, the desktop applications may be selected for inclusion in a private catalog or portfolio that may only be accessible to a subset of the end users of the service provider customer. In one example, the input may be received from an IT administrator of a business, enterprise, or other organization that receives services through the enterprise catalog service platform and/or an application fulfillment platform (i.e., an organization that is a service provider customer). In this example, the IT administrator may log into the system provider management console in order to create and/or manage one or more portfolios of applications for the use of some or all of the members of their organization. In various embodiments, the selection of desktop applications may be made by the IT administrator, and may be dependent on technical features (e.g., capabilities of the application and/or resources required to execute the application), a pricing breakdown, the applicable terms of use (e.g., licensing or subscription terms), ratings and/or reviews, the availability of support from the vendor and/or other information, including organizational needs, goals, or policies.

As illustrated in this example, the method may also include receiving, through the service provider management console, input indicating the assignment of the selected application(s) to one or more end users and/or user groups, constraints on the use of the selected application(s), and/or configuration parameter setting(s) for the portfolio, as in 740. For example, in some embodiments, constraints and/or configuration parameter settings may be specified as part of an operation to assign applications to particular users or user groups. In other embodiments, constraints and/or configuration parameters may be specified as part of a separate interaction between the IT administrator and the console (e.g., as part of a portfolio configuration operation), and information indicating the constraints and/or configuration parameter settings may be received as separate inputs through the service provider management console. In some embodiments, the constraints may indicate which (if any) of the applications in the portfolio are required to be installed by end users and which (if any) are optional. In some embodiments, the configuration parameter settings may indicate whether monitoring should be enabled for the portfolio (and/or particular applications in the portfolio) or may indicate whether end users have the option to view lists of applications that are not assigned to them and/or that are not currently available in the portfolio (e.g., third party applications that may be available through the application fulfillment platform).

As illustrated in this example, the method may also include storing information representing the assignment of the selected applications to particular end users and/or user groups, the constraints, and configuration parameter settings for the selected applications, users, and portfolio, as in 750. For example, this information may be stored in any of a variety of data structures or database tables by a storage service implemented on the service provider network. The method may also include making the selected applications available to the end user(s) through a desktop application management module interface, according to the constraints and configuration parameter settings for the selected applications and users, as in 760. In some cases, this may include installing any required applications and/or making certain applications (e.g., those applications that are assigned to a particular end user or those an end user is allowed to know about) visible and/or selectable through a desktop application management module interface or (once they are installed on an end user machine or in a virtual desktop instance) through an icon, shortcut, menu element, or other user interface mechanism or element thereof that was created on the desktop for the application and whose selection launches the application.

Note that, in some embodiments and/or for some applications, “installing” the required and/or selected applications may not include installing the application itself (i.e., an unpackaged application binary) on an end user's physical computing device, virtualized computing resource instance or virtual desktop instance, but may involve delivering some or all of the pages of program instructions of a virtualized application (e.g., using demand paging) to the end user's computing resource instance for execution by a runtime engine that is installed in the end user's computing resource instance.

As illustrated in FIG. 7, in some embodiments, the method may also include tracking the usage of the desktop applications in the portfolio and passing information about the usage of the application by various end users to a service provider billing system for subsequent use in billing the service provider customer's IT administrator for the use of those applications (as in 770). For example, the method may include generating usage reports for the applications in the portfolio automatically (e.g., periodically or in response to changes in the catalog/portfolio or application usage) or upon request. In some embodiments, the reports may be delivered through the service provider management console or desktop application management module interface (e.g., to IT administrators and/or end users) in addition to being passed to a service provider billing system. In various embodiments, the reports may indicate how many (and/or which) users are using each application, how many (and/or which) users are using each version of a particular application, the duration for which each application is used by one or more users, and/or other usage information.

As previously noted, the enterprise catalog service platforms described herein may be used to manage server products on behalf of customers and their end users instead of, or in addition to, managing desktop applications. One embodiment of a method for managing server products (e.g., server-type applications that execute on a service provider system on behalf of an end user and return a response) through an enterprise catalog service (such a service implemented by the system illustrated in FIG. 1) is illustrated by the flow diagram in FIG. 8. As illustrated at 810, in this example, the method may include an IT administrator of a service provider customer organization selecting, from a product discovery service, one or more resource stack templates that are sourced by third parties, and ingesting the resource stack templates into a product catalog owned by the IT administrator for subsequent deployment to end users in the customer organization. The method may also include ingesting one or more line-of business resource stack templates (e.g., custom resource stack templates that were developed by the customer organization) into the IT administrator's product catalog, as in 820.

As illustrated in this example, the method may include receiving (e.g., from an IT administrator of a service provider customer), through a service provider management console, input indicating the selection of one or more previously ingested resource stack templates to be included in a portfolio for subsequent access by end users (as in 830). For example, in various embodiments, the resource stack templates may be selected for inclusion in a private catalog or portfolio that may only be accessible to a subset of the end users of the service provider customer. In one example, the input may be received from an IT administrator of a business, enterprise, or other organization that receives services through the enterprise catalog service platform and/or from a resource stack management service (i.e., an organization that is a service provider customer). In this example, the IT administrator may log into the system provider management console in order to create and/or manage one or more portfolios of server products (each of which may be constructed using a respective resource stack template) for the use of some or all of the members of their organization. In various embodiments, the selection of resource stack templates may be made by the IT administrator, and may be dependent on technical features (e.g., capabilities of the server product and/or resources required to create the corresponding resource stack), a pricing breakdown, the applicable terms of use (e.g., licensing or subscription terms), ratings and/or reviews, the availability of support from the vendor and/or other information, including organizational needs, goals, or policies.

As illustrated in this example, the method may include receiving (e.g., from an IT administrator of a service provider customer), through a service provider management console, input indicating the assignment of selected resource stack template(s) to one or more end users and/or user groups, constraints on use of the selected template(s) and/or configuration parameter setting(s) for the portfolio (as in 840). For example, in some embodiments, constraints and/or configuration parameter settings may be specified as part of an operation to assign server products to particular users or user groups. In other embodiments, constraints and/or configuration parameters may be specified as part of a separate interaction between the IT administrator and the console (e.g., as part of a portfolio configuration operation), and information indicating the constraints and/or configuration parameter settings may be received as separate inputs through the service provider management console. In some embodiments, the constraints may indicate which (if any) of the server products in the portfolio are required to be installed by end users and which (if any) are optional. In some embodiments, the configuration parameter settings may indicate whether monitoring should be enabled for the portfolio (and/or particular server products in the portfolio) or may indicate whether end users have the option to view lists of server products that are not assigned to them and/or that are not currently available in the portfolio (e.g., third party products that have not yet been ingested into the enterprise catalog service platform).

As illustrated in this example, the method may also include storing information representing the assignment of the selected resource stack templates to particular end users and/or user groups, the constraints, and configuration parameter settings for the selected resource stack templates, users, and portfolio, as in 850. For example, this information may be stored in any of a variety of data structures or database tables by a storage service implemented on the service provider network. The method may also include making the selected resource stack templates available to the end user(s) through a resource stack management service console, according to the constraints and configuration parameter settings for the selected resource stack templates and users, as in 860. In some cases, this may include installing any required server products and/or making certain server products (e.g., those server products that are assigned to a particular end user or those an end user is allowed to know about) visible and/or selectable through a resource stack management service console (e.g., through icons, shortcuts, menu elements, or other user interface mechanisms or elements thereof that were created on the resource stack management service console for the server products and whose selection launches the server products).

As illustrated in FIG. 8, in some embodiments, the method may also include tracking the deployment of resource stack templates that are included in the portfolio and passing deployment information to a service provider billing system for subsequent use in billing the service provider customer's IT administrator for the use of those resource stack templates (as in 870). For example, the method may include generating reports indicating the number of resource stacks that are launched for each resource stack template in the portfolio automatically (e.g., periodically or in response to changes in the catalog/portfolio or resource stack template usage) or upon request. In some embodiments, the reports may be delivered through the service provider management console or resource stack management service console (e.g., to IT administrators and/or end users) in addition to being passed to a service provider billing system. In various embodiments, the reports may indicate how many (and/or which) users have deployed a resource stack for each resource stack template, the duration for which each resource stack instance is used by an end user, and/or other deployment/usage information.

As discussed above, an enterprise catalog service may be used to track and control costs. For example, portfolios, products, computing resource instances and resource stack template may support tagging. When a product is used, the resultant computing resource instances or resource stacks may be tagged with the portfolio, the product, the product version and a unique identifier (i.e. instanceId or stack Id). These tags may be used to filter spend data presented in a cost discovery tool, enabling the end users to track the spending for a portfolio, a product or for a single product deployment. End users may be able to view the costs on a daily, weekly or monthly basis.

For example, if an end user requests a subscription to a desktop application, and once the IT administrator has subscribed to and provisioned the application (e.g., by installing a virtualized application package on a virtual desktop), and various end users start using it, the enterprise catalog service may begin billing the IT administrator for the application (or begin metering usage for subsequent billing). For a server product, when the actual product is deployed, the enterprise catalog service may begin billing the IT administrator for the product at a pre-determined rate for the product plus the cost of the underlying infrastructure (e.g., daily, hourly, monthly, annually, or as a one-time cost).

As previously noted, in some embodiments, an application (which is sometimes referred to herein as desktop application management module) may be installed on an end user's machine or on a virtual desktop instance that provides an interface to virtualized desktop applications delivered from an application fulfillment platform. In some embodiments, this application may also provide an interface through which applications that are physically installed on the end user's machine may be launched. For example, after launching the desktop application management module (e.g., by selecting an icon or shortcut on the desktop or on a virtual desktop), an end user may, through a graphical user interface of the desktop application management module, log into the desktop application management module using their identity, view a list of applications that are available for their use (e.g., applications that they have permission to purchase, lease or subscribe to, install, and/or execute) or that may be made available for their use (e.g., applications for which they may be able to request permission to purchase, lease or subscribe to, install, and/or execute) and select on option to purchase, lease or subscribe to, install, and/or execute one of the listed applications.

One embodiment of a graphical user interface (GUI) 900 for a desktop application management module that is installed on an end user's computing resource instance, such as desktop application management module 128 illustrated in FIG. 1, is illustrated by the block diagram in FIG. 9A. In this example, an end user has chosen to view applications that are assigned to the end user or are part of a private catalog or portfolio of applications made available to the end user and/or one or more other end users by an IT administrator in the same business, enterprise, or organization (“my desktop applications”). In some embodiments, the list of applications presented by the selection of “my desktop applications” may include the union of the set of applications that have been individually and directly assigned to the end user and any applications included in portfolios with which the end user is associated (e.g., a logical private catalog for the end user), even if the end user is not aware of these associations. For example, in some embodiments, the end user may have no knowledge of (or visibility into) the concept of a portfolio, and may not know which, if any, of the applications in the end user's private catalog are included in a portfolio. In response to this selection, a list of applications is presented to the end user. In this example, the list of applications indicates, for each application, an application name, the vendor from which the application is sourced, and an available action that can be taken for the application (e.g., “install”, for an application that is not currently installed on the end user's computing resource instance, or “uninstall”, for some of the applications that are currently installed on the end user's computing resource instance). Note that for several of the applications, the action is shown as “required.” This may indicate that these applications must be installed on the end user's computing resource instance (e.g., they may have been installed automatically when the computing resource instance was configured or when the desktop application management module was launched) and cannot be uninstalled (until and unless this requirement changes). Note that one of the applications in the list (a task tracking tool) was developed by the end user's company and ingested by the service provider for management through the application fulfillment platform. Note also that GUI 900 includes a user interface element whose selection allows an end user to upload an application (e.g., an application developed by the end user or by other end users in the end user's company).

In GUI 900, applications may be listed in any order, in different embodiments, e.g., in alphabetical order by name or vendor, by application type (e.g., productivity applications, data analysis applications, line-of-business applications, etc.), or by availability (e.g., required applications, optional applications that have been installed, optional applications that have not been installed, etc.). As illustrated in this example, the end user may have the option to search the list of applications in order to display specific ones of the applications in the user interface for the desktop application management module. Note that this catalog may include customer-specific line-of-business applications (such as the task tracking tool described above); applications that were developed and/published by the service provider; applications that were developed, published, and/or otherwise sourced by an entity other than the end user's company or the service provider and that were purchased or licensed by the service provider for the benefit of service provider customer and their end users; and/or applications that were developed, published, and/or otherwise sourced by an entity other than the end user's company or the service provider and that were purchased or licensed by the end user's company for the benefit of their end users.

As illustrated in this example, an IT administrator may ingest line-of-business applications (e.g., line-of-business applications developed by their own organization) and may manage the life cycle of those applications just as they would manage the life cycle of applications sourced by other entities. For example, to ingest a new line-of-business application, the IT administrator may (e.g., through an administrator/management console of the enterprise catalog service) provide application metadata for the new application that includes a name, title, and description. An ingestion workflow may put the application through a series of automated validation steps to ensure that the software is compatible with virtual desktop instance on which it may be executed. Subsequently, once the service provider and the IT administrator approve the listing, the product may be published to the application fulfillment platform. In some embodiments, the line-of-business application may be added to an enterprise-wide or default catalog for the customer organization (e.g., one that is owned by the IT administrator and managed through the enterprise catalog service) upon ingestion, but it may be visible only within the context of the customer organization's service provider account for listing alongside other applications available to the IT administrator and end users in the customer organization in the GUI for the application fulfillment management module.

As illustrated in this example, in some embodiments the end user may (e.g., based on constraints or permissions applied by their IT administrator) have the option to view a “full application catalog.” FIG. 9B illustrates the graphical user interface 900 of FIG. 9A when the end user has chosen to view information about the full application catalog. As in the previous example, this catalog may include customer-specific line-of-business applications (such as the task tracking tool described above), applications developed and/or published by the service provider, and/or applications developed and/or published by someone other than the end user's company or the service provider. However unlike in the example illustrated in FIG. 9A, the full application catalog displayed in FIG. 9B may include customer-specific line-of-business applications, applications developed and/or published by the service provider and/or third party applications that have not been assigned to the end user or that are included in a catalog that is made available to the end user by their IT administrator (including some for which the business, enterprise, or organization does not yet have a subscription or license) instead of, or in addition to, applications that are included in a catalog or portfolio of applications that have been made available to the end user and/or one or more other end users by an IT administrator (whether or not the applications are assigned to the end user). For example, the list of applications presented in the graphical user interface illustrated in FIG. 9B includes a word processing application (word processing app C) and a spreadsheet application (spreadsheet app D) that are not currently assigned to the end user or included in the end user's private catalog that is presented in FIG. 9A. In this case, the end user may select a “request” action in order to request access to (e.g., a subscription to) one of these applications. If the application has not yet been licensed by the service provider or the end user's company, selecting this action may, if the request is approved, initiate the acquisition and/or licensing of the application by the service provider or the end user's company and the ingestion of the application into the application fulfillment platform. Note that, in some embodiments, an application may be marked as having an installation type of “request access” for one or more end users, meaning that the application is discoverable by those end users, but cannot be installed or launched by those end users until or unless a request to access the application is approved (e.g., by the IT administrator).

Note that, as illustrated in both FIG. 9A and FIG. 9B, in some embodiments, the end user may also have the option to view “notifications” through the user interface of the desktop applications management module. For example, the end user may receive a notification when a new application is made available to the end user individually, is added to a catalog or portfolio of applications that are assigned or are otherwise available to the end user, or is added to the full application catalog, or when a new generation or version of an application to which the end user is currently subscribed is made available.

As illustrated in both FIG. 9A and FIG. 9B, the end user may request one or more reports (e.g., through selection of the “Reports” item in the user interface of the desktop application management module). As described above, these reports (which provide usage information for various applications, such as those applications that are assigned or are otherwise available to the end user) may be generated on demand (e.g., in response to requests from an IT administrator or end user) or periodically, and may be presented to an IT administrator or end user when they are generated or upon request, according to various embodiments. Note that the graphical user interface 900 may, in other embodiments, display more, fewer, or different elements than those illustrated in the examples shown in FIG. 9A and FIG. 9B. For example, in some embodiments, an additional user interface element may display a list of top rated (or most heavily used) applications for this enterprise or for all customers, links to ratings or reviews of applications, or any other information about applications that are currently available to (or may be request by) the end user. In addition, the user interface elements included in a graphical user interface for a desktop application management module may, in other embodiments, take different forms (e.g., as menu items, icons, radio buttons, text boxes, check boxes, or other user interface element types) and/or may be arranged in a different order or in different positions within the GUI than the order or positions in which they are arranged in FIGS. 9A and 9B.

In some embodiments, GUI 900 illustrated in FIGS. 9A and 9B may also include a user interface mechanism (not shown) that, when selected, allows the end user to view more information about an application (e.g., one that is assigned to them, one that is included in a catalog or portfolio of applications to which they have access, or one that they have discovered but do not currently have permission to install, subscribe to, or launch). The information presented in response to selection of this option may include a description of the application, the status of the application (e.g., indicating whether it is required, is optional and assigned to the end user, is available from the enterprise catalog service but not currently assigned to the end user, or not currently available from the enterprise catalog service, in which case the end user may request a subscription), ratings for the product, reviews of the product, subscription or licensing terms, pricing information, and/or version and life cycle information, in some embodiments.

In some embodiments, once an end user logs into the desktop application management module, their applications (e.g., any application assigned to the end user) may be available and ready to use. In some embodiments, the end user may access their application just like they access any other desktop applications (e.g., through a start menu or a desktop icon or shortcut). Through the desktop application management module, the end user may be able to select one or more of the following options:

-   -   View information about applications that were made available to         the end user by their IT administrator     -   Subscribe to optional applications     -   Remove optional applications     -   Request access to additional applications that are listed in the         full application catalog, which may include applications sourced         by the service provider and/or by third parties (if enabled by         the IT administrator)     -   Back up their application and configurations (e.g.,         automatically)     -   Receive notification about applications and application updates

In some embodiments, if the IT administrator has designated an application as “required” for a given end user, it will be installed on an end user's virtual desktop instance by default, and cannot be removed. However, if the IT administrator has designated an application as “optional”, it may only be installed on the end user's virtual desktop instance if the end users choose to subscribe to the application. As noted above, if the IT administrator has enabled the full application catalog as viewable for a given end user, user group, catalog, or portfolio, the end user may be able to discover additional applications that are sourced by the service provider and/or third parties, and select a “request application” option, which may automatically submit a request to the IT administrator for the selected application.

In some embodiments, when a software vendor provides an update to the application fulfillment platform (or to the service provider) the service provider may (e.g., through the application fulfillment platform) publish the update and make it available to end users (e.g., through the desktop application management module. In some embodiments, the IT administrator may be able to control the maintenance window in which application updates are applied to the computing resource instances of its end users. In such embodiments, if an end user is using an application that is targeted for an update during the maintenance window, the end user will not experience any interruption, because the update will occur in the background. However, the next time the end user launches the application, the update will be applied. In some embodiments, there may be a notification engine within the desktop application management module that is configured to inform end users of upcoming application updates and newly available features. The notification engine may be accessed through the desktop application management module graphical user interface (e.g., using the “notifications” tab shown in FIGS. 9A and 9B), or using other mechanisms, in different embodiments. For example, if the IT administrator has made new optional applications available for end users to subscribe to, they may be notified through the desktop application management module. In some embodiments, the application fulfillment platform may preserve application state by automatically backing up applications and application data for subsequent copy or restore operations. For example, if the virtual desktop instance is rebuilt, the applications and application data may be automatically restored on the virtual desktop instance. Similarly, upon rebooting an end user's machine after a failure, the virtual desktop instance may automatically be rebuilt, and the applications and application data may be automatically restored.

In one example, an end user may (through the desktop application management module) select an option to subscribe to a particular listed application. In response, a subscribe request may be sent an application fulfillment service (e.g., a service implemented by an application fulfillment platform). In this example, the subscription request may indicate that user X on machine Y connected to domain Z requests access to the selected application. The fulfillment service may verify whether the end user is entitled to use the selected application and, if so, may initiate the execution of a “create fulfillment” workflow that delivers the requested application to the end user's physical computing device or virtual desktop instance, adds it to a default catalog for the end user's organization (e.g., a catalog owed by an IT administrator), and assigns it to the end user (or multiple end users). The workflow may also include a sequence of steps to prepare the application for launching that include registering a virtual desktop session, virtualizing the selected application, generating an icon or shortcut for the virtualized application and placing it on the end user's machine (e.g., on the desktop or on the virtual desktop) and/or adding the virtualized application to a start menu or other interface mechanism, among other actions.

One embodiment of a method for requesting and receiving access to a desktop application that is managed through an enterprise catalog service implemented by a service provider is illustrated by the flow diagram in FIG. 10. As illustrated at 1010, in this example, the method may include an end user (e.g., an end user in an organization that is a customer of the service provider) discovering, through a product discovery service interface at a service provider that is accessed from a local desktop application management module interface, a desktop product (e.g., a desktop application) that the end user wants to use. The method may include the end user initiating, through the product discovery service interface, a service provider workflow to request approval for and/or access to the desired desktop application (as in 1020).

In some embodiments, an IT administrator may use approval chains to require a manual approval prior to a product being used or a resource stack being updated or deleted. For example, an approval chain (which includes a set of steps) may be associated with a product by the IT administrator. Each step consists of a notification sent to a user, administrator or decision maker. The notification contains a link to approve or deny the request along with information about the user and the product to inform the decision to approve or deny the request. In various embodiments, approval chains may be applied to all products in a portfolio or to individual products. In some embodiments, when an attempt is made to use a server product that has an associated approval chain or to update or delete of resource stack that has an approval chain, the resource stack may be put in an “approval pending” state until it has been fully approved through the approval chain. In some embodiments, while the resource stack is in this state, the IT administrator and/or end user who initiated the operation on the product may be able to view the current approval step through the administrator/management console or end user console to track the progress of the product through the approval process. In this example, once all approvals have been accepted, the operation will continue.

As illustrated in FIG. 10, if the request is not approved and approval is required (shown as the negative exit from 1030), the method may include returning an indication that request is denied (as in 1035). However, if the request is approved or approval is not required (shown as the positive exit from 1030), the method may include the product discovery service receiving input initiating the selection and ingestion of the desired desktop application, including an agreement to the terms under which the desktop application is purchased or licensed by the service provider and/or the service provider customer (as in 1040). For example, an IT administrator of the service provider customer may select and accept an offer (which may be one of several available offers), and the selection may be dependent on technical features (e.g., capabilities of the application and/or resources required to execute the application), a pricing breakdown, the applicable terms of use (e.g., licensing or subscription terms), ratings and/or reviews, the availability of support from the vendor and/or other information.

As illustrated in this example, the method may include the product discovery service packaging the selected desktop application and adding it to a default or enterprise-wide catalog for the end user's organization that is owned and/or managed by an IT administrator within the organization on behalf of the organization (through the enterprise catalog service provided by the service provider), as in 1050. The method may include the enterprise catalog service receiving input indicating that the desktop application should be added to one or more catalogs or portfolios to which the end user has access (e.g., a logical private catalog or portfolio), or that the desktop application should be assigned to the end user (e.g., explicitly assigned to an individual end user), as in 1060. The method may also include the end user initiating, through the local desktop application management module interface, a launch of the desired desktop application, which may include installing the application (as in 1070). For example, installing the desktop application may involve installing an executable (e.g., application binary) on the end user's machine, installing an application on a virtual desktop instance, or preparing a virtualized application for execution on a virtualized computing instance by a runtime engine installed on the end user's machine or virtual desktop instance, in different embodiments.

One embodiment of a method for managing updates to desktop applications through an enterprise catalog service implemented by a service provider is illustrated by the flow diagram in FIG. 11. As illustrated at 1110, in this example, the method may include a service provider customer end user initiating a service provider workflow to request approval for and/or access to a desired desktop application. For example, the end user may request a one-time access to the desktop application or a subscription to the desktop application. In response to the request, the method may include the request being approved and the desired application being made available to the end user in a catalog or portfolio, or by being assigned directly to the end user (as in 1120). Once the desktop application has been made available to the end user, the method may include the end user launching and using the desired desktop application (which may include installing the desktop application, using any of the techniques described herein), as in 1130.

As illustrated in FIG. 11, at some point subsequent to the end user launching and using the desktop application, the method may include the end user receiving (e.g., from the enterprise catalog service through an application fulfillment platform interface) a notification that a new generation or version of the desktop application is available (as in 1140). For example, in some embodiments, notifications indicating that a new generation or version of the desktop application has been published and/or ingested by the service provider may be sent to end users of the service provider customer that are currently authorized to launch and use the desktop application. If the desktop application (or a catalog or portfolio in which it is included) is configured for automatic updates (shown as the positive exit from 1145), the method may include the enterprise catalog service atomically adding the new generation/version of application to the catalog or portfolio and/or assigning the new generation/version of the application to the end user (according to the applicable update settings, constraints, and/or configuration parameters for the application and catalogs/portfolios), as in 1150. For example, if the new generation/version of the application is a required application, or if a configuration setting for the application and/or catalog/portfolio specifies that updates should be applied automatically, the application may be updated in response to the notification of the new generation/version of the application.

As illustrated in this example, if the application (and/or a catalog or portfolio in which it is included) is not configured for automatic updates (shown as the negative exit from 1145), the end user may be able to choose whether (and/or when) to update the application. For example, if the new generation/version of the application is an optional application, or if a configuration setting for the application and/or catalog/portfolio specifies that the user is authorized to update the application, and if the end user chooses to update the application (shown as the positive exit from 1160), the method may include the end user initiating a service provider workflow to request the addition of the new generation/version of the application to the appropriate catalogs/portfolios and/or the assignment of the new generation/version to the end user, as in 1170. However, if the end user chooses not to update the application (shown as the negative exit from 1160), the method may include end user continuing to use a previously discovered generation/version of the application, as in 1165.

Note that, in some embodiments, a method similar to that illustrated in FIG. 11 may be used to manage updates to server products through an enterprise catalog service implemented by a service provider. For example, an IT administrator may (e.g., when a server product is ingested or added to a catalog or portfolio) configure the server product or catalog/portfolio for automatic updates or for manual updates (e.g., to receive notifications only) in response to a new version of the server product becoming available.

As described in detail herein, an IT administrator may in some cases retain full control of the service provider resources that are associated with a product that is provisioned for the benefit of their organization. For example, the IT administrator may have full control over the service provider accounts and roles used to provision products for their end users. The service provider resources may be provisioned in either the end user's account or in the IT administrator's account (which may be the customer organization's root account). To retain full control over the service provider resources, the IT administrator may specify (e.g., at a catalog/portfolio level or a product level), that resources should be provisioned in the IT administrator's account or the organization's root account. For example, when providing a server product that is implemented as a resource stack, the IT administrator may specify that the underlying service provider resources should be provisioned in the IT administrator's account and may provide a link to the resulting service as an “output”. For such a product, end users would be able to see that the service was created (and retrieve the corresponding URL for the service), but would not be able to view or access the service provider resources.

In some embodiments, whether a product is provisioned in the end user's account or the IT administrator's account, the IT administrator can view the products that have been provisioned from a catalog or portfolio that the IT administrator owns (e.g., by specifying an identity and access management role for products that are provisioned under the end user's account). For products built from resource stack templates, the IT administrator may also track product usage through the administrator/management console. For example, the IT administrator may be able view information about the products, the account(s) in which they have been provisioned, the health state, and the costs currently associated with the product.

FIG. 12 illustrates an example of the information presented to an end user through a graphical user interface (GUI 1200) of a resource stack management service console, according to at least some embodiments. In this example, the information may be presented to an end user who wishes to search for, select, and launch a service (e.g., a server product) that is managed by an enterprise catalog service (e.g., in response to selection of the “my products” tab near the top of the display). More specifically, the end user has chosen to filter their search results by choosing “Computational services” from among multiple product type options. In this example, GUI 1200 also presents options for the end user to upload a resource stack template (“upload template”), to generate and/or view reports (e.g., server product deployment reports), and to view (and, in some cases, take action in response to) notifications. Note that in some embodiments, the end user may also be presented with an option to create a resource stack template, while in other embodiments, only an IT administrator or other privileged user may be allowed to create a resource stack template (e.g., through a management interface of the enterprise catalog service).

The information presented in this example includes, in one portion of the display, a list of server products (e.g., server-type applications that execute on a service provider system on behalf of an end user and return a response), each of which may be constructed using a respective resource stack template, along with the vendors that developed or published the server products (or corresponding resource stack templates) and/or from which they were obtained, and user interface elements that may be selected if the end user would like to launch or update a particular one of the listed server products. More specifically, this portion of the display presents a list of computational services for selection by the end user, including a data analysis package A from vendor ABC, a graphics processing tool from vender LMN, and a statistical analysis package that was developed by the end user's organization (e.g., a customer-specific line-of-business service) and was previously uploaded to, and ingested by, the enterprise catalog service. In this example, if the end user were to select an option to launch one of these server products, this may initiate a workflow to provision and deploy a resource stack for the selected service, according to a resource stack template for the selected service (e.g., one that is stored in a private catalog or portfolio to which the end user has access).

One embodiment of a method for requesting and launching a server product that is managed through an enterprise catalog service implemented by a service provider is illustrated by the flow diagram in FIG. 13. As illustrated at 1310, in this example, the method may include an end user selecting, from within a resource stack management service console, a server product to be launched from a set of products to which the end user has access (e.g., a private catalog or portfolio of server products). In response to the selection, the method may include sending (e.g., by the resource stack management service console to the resource stack management service) a request to launch the selected product, which indicates a resource stack template for the product (as in 1320). The method may include the resource stack management service receiving the request to construct a resource stack from the resource stack template for the product, and beginning construction of a resource stack on behalf of the end user in the end user's account (e.g., based on metadata in the template and according to the end user's permissions), as in 1330. Note that, in this example, the resources of the resource stack are provided by the service provider (e.g., they are implemented on service provider resources).

As illustrated in FIG. 13, the method may include the resource stack management service determining the dependencies between the resources defined in the resource stack template and/or the order in which the defined resources should be added to the resource stack (as in 1340). For example, the resource stack template being used to construct the resource stack may define links between the resources that will be subsequently used in configuring resources of a resource stack to communicate with one another over a network, transmit requests, receive responses and otherwise interoperate. In other words, the template may define connections of the resource stack, such as a network topology for use with the resource stack that defines connectivity and/or communication paths available to resources within the resource stack.

As illustrated in this example, the method may include the resource stack management service accessing one of the resources indicated in the resource stack template, provisioning it, and integrating it into the resource stack that is under construction (e.g., in accordance with the determined order, specified dependencies, or other application constraints or configuration parameter values), as in 1350. Until and unless the resource stack is complete, the method may include repeating the operations illustrated at 1350 for each of the resources indicated in the resource stack template. This is illustrated in FIG. 13 by the feedback from the negative exit of 1360 to 1350. Once the resource stack is complete (shown as the positive exit from 1360), the method may include the resource stack management service enabling the resource stack for activation by the end user, after which the end user can terminate (delete) or update the running resource stack, as desired (as in 1370).

As previously noted, products selected from the enterprise catalog service and launched on behalf of end users may be provisioned and/or executed under the end user's account, roles, and permissions or using the account, roles, and permissions of another user (e.g., the IT administrator or another user with higher permission levels than the end user). In various embodiments of the enterprise catalog service, some or all of the following use cases may be supported:

-   -   1. An end user selects and launches a product from a catalog or         portfolio and the resource stack (and resources) are created in         the end user's account. In this case, all operations of the         resource stack management service, as well as operations of         underlying services within resource stack management service         and/or the enterprise catalog service, are performed as the end         user (using forward access sessions).     -   2. An end user selects and launches a product from the catalog         or portfolio that has an identity and access management (IAM)         role associated with it. In this case, all operations of the         resource stack management service, as well as operations of         underlying services within resource stack management service         and/or the enterprise catalog service, are performed using the         IAM role specified by the product (e.g., by assuming that IAM         role). This may enable administrators to define products that         contain an array of service provider resources without the end         user having IAM permissions to the underlying services. In this         case, the end user may only need access to the enterprise         catalog service APIs.     -   3. As an extension of use case 2 above, the role associated with         a product may be in a different account from the end-user. This         may allow for “managed service” scenarios in which the end user         controls the (create, update, delete) life cycle of the resource         stack, but does not have access to, or even need to know about,         the resources that are being used to implement the resource         stack.

In the latter two cases, the service catalog runtime may act as a trusted entity allowing administrators to define IAM policies for the roles that only allow the service catalog runtime to assume them. This may allow administrators to lock down end user accounts so that they may only launch and manage services through the service catalog. In some embodiments, the catalog service may store metadata about the product (name, description, etc.), and the service catalog runtime may be responsible for defining and storing additional information about a product. For example, the service catalog runtime may be responsible for defining the raw resource stack template that defines the resources that must be created for the product (which may include any resource supported by the resource stack management service other than IAM resources), resource stack constraints, a parameter grouping document, and/or an IAM role that the service catalog runtime will assume when the product is acted upon. Note that, although constraints live inside the template, constraints may also be added at several levels within the service catalog, and the constraints documents may be joined together as part of processing the inputs when a stack is launched or updated. Among other things, the constraints may define what values a user may pass into the parameters during construction. The parameter grouping document may define the ordering/grouping of parameters for the console when rendering them to the end user. This feature may allow the creator of the product to have some control over how these options are presented in the console when a user is creating a resource stack.

In various embodiments, the resource stack management service may expose any or all of the following APIs:

-   -   LaunchStack—This API creates a resource stack for the provided         product.     -   TerminateStack—This API deletes a specified resource stack and         all resources associated with it.     -   DescribeStack—This API provides detailed information about a         resource stack (e.g., input parameters, outputs, etc.).     -   ListStackEvents—This API provides a list of events for a         resource stack (e.g., resource creation, updates, etc.). In some         embodiments, this list may be filtered for certain users (e.g.,         they may not be able to see the service provider resources).     -   ListStacks—This API lists all of the resource stacks for the         account, along with basic information about them.     -   UpdateStack—This API updates a product to a new version of the         product.     -   UpdateStackConfiguration—This API allows updates to the input         parameters of a stack, giving IT administrators more control         over what their end users can do.

One embodiment of a method for launching a server product through an enterprise catalog service that supports identity and access management roles is illustrated by the flow diagram in FIG. 14. As illustrated at 1410, in this example, the method may include an end user selecting, from within a resource stack management service console, a server product to be launched from a set of products to which the end user has access (e.g., a private catalog or portfolio of server products). The method may include sending (e.g., from the resource stack management service console to the resource stack management service) a request to launch the selected product, where the request indicates a resource stack template for the product, as in 1420. In other words, the underlying resources that will be used to implement the server product (e.g., a service) may be defined in a resource stack template that is specified in the request.

As illustrated in this example, if the selected product has an associated identity and access management role (shown as the positive exit from 1430) and the end user has the appropriate identity and access management permissions (e.g., permission to access the underlying resources defined in the resource stack template), shown as the positive exit from 1435, the method may include the resource stack management service provisioning the required resources and constructing a resource stack for the product under the end user's account based on the resource stack template, where the resource stack management service performs these operations as the end user (as in 1450). Similarly, if the selected product does not have an associated identity and access management role (shown as the negative exit from 1430), the method may include the resource stack management service provisioning the required resources and constructing a resource stack for the product under the end user's account based on the resource stack template, where the resource stack management service performs these operations as the end user (as in 1450).

If the selected product has an associated identity and access management role (shown as the positive exit from 1430), but the end user does not have the appropriate identity and access management permissions (e.g., permission to access the underlying resources), shown as the negative exit from 1435, the method used to launch the selected server product may be dependent on whether or not the role is associated with a different service provider account (i.e., an account that is different from the end user's service provider account), as in 1440. For example, if the role is associated with a different service provider account (shown as the positive exit from 1440), the method may include the resource stack management service provisioning the required resources and constructing a resource stack for the product under the other account based on the resource stack template, where the resource stack management service performs these operations under an assumed role, as in 1470. However, if the role is not associated with a different service provider account (shown as the negative exit from 1440), the method may include the resource stack management service provisioning the required resources and constructing a resource stack for the product under the end user's account based on the resource stack template, where the resource stack management service performs these operations under an assumed role, as in 1460.

As illustrated in this example, in some embodiments, once the resource stack has been provisioned (as shown in elements 1450, 1460, or 1470 in FIG. 14), the method may include the resource stack management service enabling the resource stack for activation by the end user, after which the end user can terminate (delete) or update the running stack as desired (as in 1480). In other words, in some embodiments, even if an end user does not have the specified identity and access management role for a particular server product, the end user may be able to use the product and control the lifetime of the constructed stack. However, in this case, the end user might not be able to directly access the underlying resources of the constructed stack.
